NEW
Qumranet, a technology startup began the development of KVM and was subsequently acquired by Red Hat in 2008. Red Hats first release was v 2.1 in 2009 with an update in 2010 which included the virtual technical workstation capabilities. The 3.0 release in 2012 was a major milestone in porting the RHV-M manager from .NET to Java (and fully open-sourcing) alongside other improvements.
RHV 3.1 removed all requirements of any Windows-based infrastructure, but still support Microsoft Active Directory for user authentication, administration, VDI, etc. RHV 3.1 also provided a RESTful API for integration.
Since RHV 3.2, Red Hat has provided many feature enhancements, improvements in scale, enhanced reliability and integration points (hooks, OpenStack etc) documented in the matrix.
While not as large as e.g. the VMware and Microsoft ecosystem there are a large number of ISVs with products currently integrated into RHV, including Acronis for Backup/DR/Migration, Symantec Storage Foundation and Tintri for Storage, BMC TrueSight for capacity optimization, Igel, Wyse and other thin client vendors have SPICE (RHVs remote viewing protocol) integrated in some of their product offerings. Major OEM hardware vendors like IBM and HP support RHV (e.g. IBM has part numbers for all of RHVs subscription offerings). Additionally RHV enables third party plug-ins Recent plug-ins include:
- BMC connector for RHV-M REST API to collect data for managing RHV boxes without having to install an agent.
- HP OneView for Red Hat Virtualization (OVRHV) UI plug-in that that allows you to seamlessly manage your HP ProLiant infrastructure from within RHV Manager and provides actionable, valuable insight on underlying HP hardware (HP Insight Control plug-in is also available).
- NetApp Virtual Console enables rapid cloning of NetApp virtual machines, and allows NFS storage discovery, provisioning and modification from within Red Hat Virtualization Manager.
- Symantec Storage Foundation that delivers storage Quality of Service (QoS) at the application level and maximizes your storage efficiency, availability and performance across operating systems. This includes Symantec Cluster Server provides automated disaster recovery functionality to keep applications up and running. Cluster Server enables application specific fail-over and significantly reduces recovery time by eliminating the need to restart applications in case of a failure.
- Tenable Network Securitys Nessus Audit for RHV-M which queries the RHV API and reports that information within a Nessus report.
- Ansible RHV module that allows you to create new instances, either from scratch or an image, in addition to deleting or stopping instances on the RHV platform.

|
Yes (except with CPU pass-through)
Each cluster is configured with a minimal CPU type that all hosts in that cluster must support (you specify the CPU type in the RHV-M GUI when creating the cluster). Guests running on hosts within the cluster all run on this CPU type, ensuring that every guest can be live migrated to any host within the cluster. This cannot be changed after creation without significant disruption. All hosts in a cluster must run the same CPU type (Intel or AMD).

Maintenance mode is a core feature to prepare a host to be shut down safely.
vSphere Quick Boot is a new innovation that restarts the ESXi hypervisor without rebooting the physical host. (new)
|
Yes (LB) - Built-in (CPU) and Scheduler for custom
Yes - a policy engine determines the specific host on which a virtual machine runs. The policy engine decides which server will host the next virtual machine based on whether load balancing criteria have been defined, and which policy is being used for that cluster. RHV-M will use live migration to move virtual machines around the cluster as required.
From RHV-M 3.3 a new scheduler handles virtual machine placement, allowing users to create new scheduling policies, and also write their own logic in Python and include it in a policy.
- The new scheduler serves scheduling requests for running or migrating virtual machines according to a policy.
- The scheduling policy also includes load balancing functionality.
- Scheduling is performed by applying hard constraints and soft constraints to get the optimal host for that request at a given point of time
- The infrastructure allowing users to extend the new scheduler, is based on a service called ovirt-scheduler-proxy. The services purpose is for RHV admins to extend the scheduling process with custom python filters, weight functions and load balancing modules.
- Every cluster has a scheduling policy. Prior to 3.3, there were only three main policies - None, Even distribution, and Power saving - and now administrators can create their own policies or use the built-in policies which were extended to support new capabilities such as shutting down servers for power saving policy.
The load balancing process runs once every minute for each cluster in a data center. You can disable automatic migration for individual vm or pin them to specific hosts.
You can choose to set the policy as either even distribution or power saving, but NOT both.

Automated Live Migration
Details

Yes (DRS) - CPU, Mem
VM Distribution: Enforce an even distribution of VMs.
Memory Metric for Load Balancing: DRS uses Active memory + 25% as its primary metric.
CPU over-commitment: This is an option to enforce a maximum vCPU:pCPU ratios in the cluster.
Network Aware DRS - system look at the network bandwidth on the host when considering making migration recommendations.
Storage IO Control configuration is now performed using Storage Policies and IO limits enforced using vSphere APIs for IO Filtering (VAIO).
Storage Based Policy Management (SPBM) framework, administrators can define different policies with different IO limits, and then assign VMs to those policies.
|
Yes (Power Saving)
When Power saving is enabled in a cluster it distributes the load in a way that consolidates virtual machines on a subset of available hosts. This enables surplus hosts that are not in use to be powered down, saving power. You can set the threasholds in the RHV-M GUI to specify the Minimum Service Level a host is permitted to have.
You must also specify the time interval in minutes that a host is permitted to run below the minimum service level before remaining virtual machines are migrated to other hosts in the cluster - as long as the maximum service level set also permits this.
LIMITATIONS:
- You can enable either Load Balancing or Power Savings on a cluster but not both concurrently.
- Currently only CPU utilization is considered.

Storage Live Migration is officially supported since RHV 3.2 that allowed migration of virtual machine disks to different storage devices while the virtual machine is running.
RHV 3.3 added the ability to do it to several disks of the same vm concurrently.
RHV 3.4 added the ability to do cold move between any two storage domains in the same DC (e.g., NFS and iSCSI) and Storage Live Migration between types of file domains (NFS/POSIX/Gluster) or block domains (FCP/iSCSI).
RHV 3.5 added the option to move an entire storage domain between DCs or even between setups.

Storage Migration
Details
|
Yes (Live Storage vMotion)
Storage vMotion allows to perform live migration of virtual machine disk files (e.g. across heterogeneous storage arrays) without vm downtime. Storage DRS handles initial vmdk placement and gives migration recommendations to avoid I/O and space utilization bottlenecks on the datastores in the cluster. The migration is performed using storage vMotion.
|
200 hosts/cluster
That is the supported maximum number of hosts per RHV DataCenter and also per cluster (the theoretical KVM limit is higher).

HA/DR |
|
|
|
|
max 64 nodes / 8000 vm per cluster
Up to 64 nodes can be in a DRS/HA cluster, with a maximum of 8000 vm/cluster
|
Yes (HA)
High availability is an integrated feature of RHV and allows for virtual machines to be restarted in case of a host failure.
HA has to be enabled on a virtual machine level. You can specify levels of priority for the vm (e.g. if resources are restrained only high priority vm are being restarted). Hosts that run highly available vm have to be configured for power management (to ensure accurate fencing in case of host failure).
Fencing Details: When a host becomes non-responsive it potentially retains the lock on the virtual disk images for virtual machines it is running. Attempting to start a virtual machine on a second host could cause data corruption. Fencing allows RHV-M to safely release the lock (using a fence agent that communicates with the power management card of the host) to confirm that a problem host has truly been rebooted.
RHV-M gives a non-responsive host a grace period of 30 seconds before any action is taken in order to allow the host to recover from any temporary errors.
Note: The RHV-M manager needs to be running for HA to function (unlike e.g. VMware HA or Hyper-V HA that do not rely on vCenter / VMM for the failover capability), also HA can not be enabled on the cluster level.

Yes (VMware HA)
vSphere 6.5 Proactive HA detect hw condition evacuate host before failure (plugin provided OEM vendors)
Quarantine mode - host is placed in quarantine mode if it is considered in degraded state
Simplified vSphere HA Admission Control - 'Percentage of Cluster Resources' admission control policy
vSphere 6.0
- Support for Virtual Volumes – With Virtual Volumes a new type of storage entity is introduced in vSphere 6.0.
- VM Component Protection – This allows HA to respond to a scenario where the connection to the virtual machine’s datastore is impacted temporarily or permanently.
“Response for Datastore with All Paths Down”
“Response for Datastore with Permanent Device Loss”
- Increased scale – Cluster limit has grown from 32 to 64 hosts and to a max of 8000 VMs per cluster
- Registration of “HA Disabled” VMs on hosts after failure.
VMware HA restarts virtual machines according to defined restart priorities and monitors capacity needs required for defined level of failover.
vSphere HA in vSphere 5.5 has been enhanced to conform with virtual machine-virtual machine anti-affinity rules. Application availability is maintained by controlling the placement of virtual machines recovered by vSphere HA without migration. This capability is configured as an advanced option in vSphere 5.5.
vSphere 5.5 also improved the support for virtual Microsoft Failover Clustering (cluster nodes in virtual machines) - note that this functionality is independent of VMware HA and requires the appropriate Microsoft OS license and configuration of a Microsoft Failover Cluster. Microsoft clusters running on vSphere 5.5 now support Microsoft Windows Server 2012, round-robin path policy for shared storage, and iSCSI and Fibre Channel over Ethernet (FCoE) for shared storage.
While not obvious to the user - with vSphere 5, HA has been re-written from ground-up, greatly reducing configuration and failover time. It now uses a one master - all other slaves concept. HA now also uses storage path monitoring to determine host health and state (e.g. useful for stretched cluster configurations).
|
Yes (HA, WatchDog)
RHV supports watchdog device for linux guests that restarts virtual machines in case of OS failure. High availability (in addition to monitoring physical hosts) also monitors all virtual machines, so if the virtual machines operating system crashes, a signal is sent to automatically restart the virtual machine, but this is with host change.

This can be either done manually by entering maintenance mode for the individual hosts or using a automated process of scheduling and applying updates to the cluster by setting hosts to maintenance mode in round-robin fashion (like e.g. with VMware Update Manager).
In RHEL Hypervisor hosts Patching is done via the normal patching processes via RHN or Satellite. Reboot can either be done manually or scheduled in round-robin fashion.

Yes; Including RAM
RHV 3.1 introduced the new ability to take Live Snapshots of VMs and has an enhanced Snapshot management interface (maintained with 3.3).
New in RHV 3.3: Snapshots now include the state of a virtual machines memory as well as disk. In addition a new Create Snapshot button has been added to the action panel of the Virtual Machines tab, and as a context menu item when a virtual machine is selected.
New in RHV 3.4: The admin portal now allows to preview, commit and manage snapshots of individual disks within a VM.
New in RHV 3.5: Ability to Live Merge snapshots, allowing to remove intermediate snapshots while VM is running
Taking a snapshot in RHV involves the following possible actions:
- Creation (obviously)
- Previews (involves previewing a snapshot to determine whether or not to restore the system to this snapshot - when it is previewed, a new (COW) preview layer is copied from the snapshot being previewed. The guest interacts with the preview instead of the actual snapshot volume. The preview can then be committed to restore the
guest data to the state captured in the snapshot or alternatively the admin can select Undo to discard the preview layer of the viewed snapshot.
- Deletion (deleting a restoration point that is no longer required)
Notes for Live Snapshots:
- VM with a guest agent that supports quiescing can ensure filesystem consistency across live snapshots. Red Hat Network registered Red Hat Enterprise Linux guests can install the qemu-guest agent to enable quiescing before snapshots (VDSM uses libvirt to communicate with the agent to prepare for a snapshot).
- All live snapshots are attempted with quiescing enabled. If the snapshot command fails because there is no compatible guest agent present, the live snapshot is re-initiated without the use-quiescing flag.
Please note: When a virtual machine is reverted with quiesced filesystems, it boots cleanly with no filesystem check required.
Reverting the previous snapshot using an un-quiesced filesystem however requires a filesystem check on boot.

Backup API
From RHV 3.3 there is a API set for third-party tools that offer backup, restore, and replication.
For backup, a snapshot of a virtual machines disk is created then attached to a virtual appliance. For restore, disks are attached to a virtual appliance, the data is restored to the disks, then the disks are attached to a virtual machine.
Tools are from enterprise companies such as Tintri, Acronis, Symantec, etc. From RHV 3.3 there is configuration support for add/edit/delete storage connections to enable multi-pathing, hardware changes, simpler failover to remote sites, and array-based replication.
RHV-M 3.5 fully supports Acronis Backup & Recovery that provides image-based backup, disaster recovery (recover the whole VM) and data protection (recover selected files).

No
There is no integrated backup in RHV Manager.
Use traditional backup methods to protect your virtual machines and hosts (e.g. backup agents for network based backups in individual virtual machines and RHEL hosts). However you can of course export virtual machines and templates onto the export domain (NFS).
Background: Export domains are temporary storage repositories that are used to copy and move images between data centers and RHV environments. They can be used to backup virtual machines. An export domain can be moved between data centers, however, it can only be active in one data center at a time. Support for export storage domains backed by storage on anything other than NFS is being deprecated - new export storage domains must be created on NFS storage.
Additionally a tool for backing up and restoring RHV Manager database and certificates is available.

Yes, CloudInit and Glance support - NEW
NEW
In RHV by default, virtual machines created from templates use thin provisioning.
In the context of templates, thin provisioning of vm means copy on write (aka linked clone or difference disk) rather than a growing file system that only takes up the storage space that it actually uses (usually referred to as thin provisioning). All virtual machines based on a given template share the same base image as the template and must remain on the same data domain as the template. Do NOT delete the template if you have created virtual machines in this way from it as the vm depend on the existence of the base image!
You can however specify to deploy the vm from template as clone - which means that a full copy of the vm will be deployed. When selecting to clone you can then select thin (sparse) or pre-allocated provisioning of the full clone. Deploying from template as clone results in independence from the base image but space savings associated with using copy on write approaches are lost.
Important: The image used to create templates for RHV must be generalized e.g. using the Sysprep tool (for Windows) or sys-unconfig (for Linux). This approach is similar to the deployment with e.g. SCVMM (different to VMware, where the generalization and customization of the vm is done on deployment, allowing for a quick, direct conversion of a template to a vm and vice versa). With RHV, changes to the template image require a deployment, applying changes/updates with subsequent generalization, then a conversion back into a template.
While not the same as a classic template, RHV 3.3 introduced support for cloud-init, which facilitates the provisioning of virtual machines by performing the initial setup of networking, SSH keys, timezones, user data injection, and more.
In RHV 3.5 support was added consume (use), export and share images with Glance. Glance image services include discovering, registering, and retrieving virtual machine images.

Comment: CloudForms (fee based cloud offering) has components called Deployable - defined as an Application deployment definition that contains one or more assemblies and meta-data configuration; this configuration specializes a deployment by qualifying it for a specific targeted infrastructure. A Deployable is essentially made of one or more Assemblies with configuration data. Each Assembly is made of one or more Templates and configuration. Each Template lists the software and configuration data. An Assembly optionally indicates the services that it defines or requires. Some of the configuration data may be defined a the time of instance launch.

The policy-driven control plane is the management layer of the VMware software-defined storage model, which automates storage operations through a standardized approach that spans across the heterogeneous tiers of storage in the virtual data plane.
Storage Policy-Based Management (SPBM) is VMware’s implementation of the policy-driven control plane which provides common management over:
- vSphere Virtual Volumes - external storage (SAN/NAS)
- Virtual SAN – x86 server storage
- Hypervisor-based data services – vSphere Replication or third-party solutions enabled by the vSphere APIs for IO Filtering.

- Quota provides a way for the Administrator to limit the resource usage in the System. Quota provides the administrator a logic mechanism for managing resources allocation for users and groups in the Data Center.
This mechanism allows the administrator to manage, share and monitor the resources in the Data Center from the engine core point of view.
- vNIC profile allows the user to limit the inbound and outbound network traffic in virtual NIC level.
- CPU profile limits the CPU usage of a virtual machine.
- Disk profile limit the bandwidth usage to allocate the bandwidth in a better way on limited connections.
- CPU shares is a user defined number that represent a relative metric for allocating CPU capacity. It defines how often a virtual machine will get a time slice of a CPU when there is no CPU idle time.

SELinux, iptables, VLANs, Port Mirroring
The RHV Hypervisor has various security features enabled. Security Enhanced Linux (SELinux) and the iptables firewall are fully configured and on by default. SELinux and sVirt adds security policy in kernel for effective intrusion detection, isolation and containment (SELinux is essentially a set of patches to the Linux kernel and some utilities to incorporate a strong, flexible mandatory access control architecture into the major subsystems of the kernel. e.g. with SELinux you can give each qemu process a different SELinux label to prevent a compromised qemu from attacking other processes and also allows you to label the set of resources that each process can see , so that a compromised qemu can only attack its own disk images.)

Agent-based (RHEL), CIM, SNMP
It is possible to use OEM vendor supplied tools, e.g. hardware monitoring utilities / agents, provided that the RHEL-based hypervisor is used.
RHV-H does not provide the tools and libraries that various tools depend upon but has basic CIM support for Systems Management. While it will not offer customizations delivered by dedicated OEM CIM providers, CIM management is available in RHV-H (RHV-H cannot be customized today to include third party CIM support). Red Hat uses the open source libcmpiutil as the CIM provider in RHV-H.
RHV-M integrates with 3rd party plug-ins that can provide systems management. For example HP OneView for Red Hat Virtualization (OVRHV) UI plug-in that that allows you to seamlessly manage your HP ProLiant infrastructure from within RHV Manager and provides actionable, valuable insight on underlying HP hardware (HP Insight Control plug-in is also available).

KVM with RHV-H or RHEL - details here
With RHV 3.5 virtualization hosts must run version 6.5, or later (of either): Red Hat Virtualization Hypervisor, or Red Hat Enterprise Linux Server.
RHV is based on the Kernel-based Virtual Machine (KVM) hypervisor and the oVirt open virtualization management platform (project started at Red Hat and released to the open source community). KVM is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, that provides the core virtualization infrastructure and a processor specific module. The kernel component of KVM is included in mainline Linux, as of 2.6.20.
RHV hosts can be either based on full Red Hat Enterprise Linux 6 based systems with KVM enabled or purpose built RHV-H (hypervisor) hosts. RHV-H is a bare metal, image-based, small-footprint (

Yes (enhanced APD and PDL) PDL AutoRemove
vSphere uses natively integrated multi-path capability or can take advantage of vendor specific capabilities using vStorage APIs for Multipathing.
By default, ESXi provides an extensible multipathing module called the Native Multipathing Plug-In (NMP). Generally, the VMware NMP supports all storage arrays listed on the VMware storage HCL and provides a default path selection algorithm based on the array type. The NMP associates a set of physical paths with a specific storage device, or LUN. The specific details of handling path failover for a given storage array are delegated to a Storage Array Type Plug-In (SATP). The specific details for determining which physical path is used to issue an I/O request to a storage device are handled by a Path Selection Plug-In (PSP). SATPs and PSPs are sub plug-ins within the NMP module. With ESXi, the appropriate SATP for an array you use will be installed automatically. You do not need to obtain or download any SATPs.
PDL AutoRemove: Permanent device loss (PDL) is a situation that can occur when a disk device either fails or is removed from the vSphere host in an uncontrolled fashion. PDL detects if a disk device has been permanently removed. When the device enters this PDL state, the vSphere host can take action to prevent directing any further, unnecessary I/O to this device. With vSphere 5.5, a new feature called PDL AutoRemove is introduced. This feature automatically removes a device from a host when it enters a PDL state.

SPM and support for shared FS; manual SPM role assigment
A host known as the Storage Pool Manager (SPM) manages access between hosts and storage.
The SPM host is the only node that has full access within the storage pool; the SPM can modify the images data, and meta-data and the pools meta-data.
In RHV 3.3 ability was added to manually assigned or re-assigned the Storage Pool Manager role to hosts, using the administration portal or via the REST API.
Additionally RHV has the capability of using any shared file system that the Linux kernel supports (support varies depending on vendor and implementation). For example, IBMs GPFS could be used as a backing store for virtual machines, configured as a POSIX file system for the Storage Domain. Other shared file systems like GFS, future versions of GlusterFS (Red Hat Storage) are considerations, as well. This provides maximum flexibility between traditional NAS (NFS), direct-to-block (standard RHV FC/iSCSI/SAS) and shared file systems (POSIX).
Background: Prior to Red Hat Virtualization 3.1, SPM exclusivity (ensuring the existence of a single arbitrator to avoid data corruption) was maintained and tracked using a feature called safelease. Safe lease only maintained exclusivity of one resource, the SPM role.
Sanlock provides the same functionality, but treats the SPM role as one of the resources that can be locked while allowing additional resources to be locked. Applications that require resource locking can register with Sanlock.

Booting from SAN is possible, provided that the HBA(s) present this ability to the BIOS. In other words, provided the OS can be booted via the LUN(s) provided by the HBA(s) then there should be no problem. When extra LUN(s) are presented to the hypervisors to use as shared storage, RHV will only allow un-used LUNs to be accepted into the storage domain, therefore its possible to both boot from SAN and use the same storage paths for shared storage in RHV.

RAW, Qcow2
RHV supports two storage formats: RAW and QCOW2
In an NFS data center the Storage Pool manager (SPM) creates the virtual disk on top of a regular file system as a normal disk in preallocated (RAW) format. Where sparse allocation is chosen additional layers on the disk will be created in thinly provisioned Qcow2 (sparse) format.
For iSCSI and SAN (block), the SPM creates a Volume group (VG) on top of the Logical Unit Numbers (LUNs) provided. During the virtual disk creation, either a preallocated format (RAW) or a thinly provisioned Qcow2 (sparse) format is created
Background: QCOW (QEMU copy on write) decouples the physical storage layer from the virtual layer by adding a mapping between logical and physical blocks. This enables advanced features like snapshots. Creating a new snapshot creates a new copy on write layer, either a new file or logical volume, with an initial mapping that points all logical blocks to the offsets in the backing file or volume. When writing to a QCOW2 volume, the relevant block is read from the backing volume, modified with the new information and written into the new snapshot QCOW2 volume. T hen the map is updated to point to the new place.
Benefits QCOW2 offers over using RAW representation include:
- Copy-on-write support (volume only represents changes to a disk image).
- Snapshot support (volume can represent multiple snapshots of the images history).
RAW
The RAW storage format has a performance advantage over QCOW2 as no formatting is applied to images stored in the RAW format (reading and writing images stored in RAW requires no additional mapping or reformatting work on the host or manager. When the guest file system writes to a given offset in its virtual disk, the I/O will be written to the same offset on the backing file or logical volume. Note: Raw format requires that the entire space of the defined image be preallocated (unless using externally managed thin provisioned LUNs from a storage array).
A virtual disk with a preallocated (RAW) format has significantly faster write speeds than a virtual disk with a thin provisioning (Qcow2) format. Thin provisioning takes significantly less time to create a virtual disk. T he thin provision format is suitable for non-IO intensive virtual machines.

Virtual Disk Format
Details

vmdk, raw disk (RDM)
VMware Virtual Machine Disk Format (vmdk) and RAW Disk Mapping (RDM) - essentially a raw disk mapped to a proxy (making it appear like a VMFS file system)
|
Default max virtual disk size is 8TB (but its configurable in RHV DB)
The default maximum supported virtual disk size is 8TB in RHV 3.5 (but its configurable in RHV DB)
With the added the virtio-scsi support in 3.3, Red Hat also supports now 16384 logical units per target.
File level disk size remains unlimited by VDSM, the limits of the underlying filesystem do however apply.

|
64TB
vSphere is increasing the maximum size of a virtual machine disk file (VMDK) from 2TB - 512 bytes to the new limit of 64TB. The maximum size of a virtual Raw Device Mapping (RDM) is also increasing, from 2TB - 512 bytes to 64TB in physical compatibility and 62TB in virtual compatibility. Virtual machine snapshots also support this new size for delta disks that are created when a snapshot is taken of the virtual machine.
|
Yes
During the virtual disk creation, either a preallocated format (RAW) or a thinly provisioned Qcow2 (sparse) format can be specified.
A preallocated virtual disk has reserved storage of the same size as the virtual disk itself. The backing storage device (file/block device) is presented as is to the virtual machine with no additional layering in between. This results in better performance because no storage allocation is required during runtime. On SAN (iSCSI, FCP) this is achieved by creating a block device with the same size as the virtual disk. On NFS this is achieved by filling the backing hard disk image file with zeros. Pre-allocating storage on an NFS storage domain presumes that the backing storage is not Qcow2 formatted and zeroes will not be deduplicated in the hard disk image file. (If these assumptions are incorrect, do not select Preallocated for NFS virtual disks).
For sparse virtual disks backing storage is not reserved and is allocated as needed during runtime. This allows for storage over commitment under the assumption that most disks are not fully utilized and storage capacity can be utilized better. This requires the backing storage to monitor write requests and can cause some performance issues. On NFS backing storage is achieved simply by using files. On SAN this is achieved by creating a block device smaller than the virtual disks defined size and communicating with the hypervisor to monitor necessary allocations. This does not require support from the underlying storage devices.

The maximum size of a virtual Raw Device Mapping (RDM) is also increasing, from 2TB - 512 bytes to 64TB in physical compatibility and 62TB in virtual compatibility. Virtual machine snapshots also support this new size for delta disks that are created when a snapshot is taken of the virtual machine.

Yes
Thin provisioning allowing for disk space saving through allocation of space based on usage (not pre-allocation).
VMFS6 - Automatic Space Reclamation
|
Yes (via Hooks)
N_Port ID Virtualization (NPIV) is a function available with some Fibre Channel devices. NPIV shares a single physical N_Port as multiple N_Port IDs. NPIV provides similar functionality for Host Bus Adaptors (HBAs) that SR-IOV provides for network interfaces. With NPIV, virtualized guests can be provided with a virtual Fibre Channel initiator to Storage Area Networks (SANs).
Note: NPIV is supported via the scripted hooks mechanism, in which many additional advanced features can be implemented. Future versions of RHV will include access to such features via the graphical user interface.

|
|
|
|
Yes (RDM only)
NPIV requires RDM (Raw Disk Mapping), it is not supported with VMFS volumes. NPIV requires supported switches (not direct storage attach).
|
Yes
In RHV by default, virtual machines created from templates use thin provisioning. In the context of templates, thin provisioning of vm means copy on write (aka linked clone or difference disk) rather than a growing file system that only takes up the storage space that it actually uses (usually referred to as thin provisioning). All virtual machines based on a given template share the same base image as the template and must remain on the same data domain as the template.
You can however specify to deploy the vm from template as clone - which means that a full copy of the vm will be deployed. When selecting to clone you can then select thin (sparse) or pre-allocated provisioning of the full clone. Deploying from template as clone results in independence from the base image but space savings associated with using copy on write approaches are lost.
A virtual disk with a preallocated (RAW) format has significantly faster write speeds than a virtual disk with a thin provisioning (Qcow2) format. Thin provisioning takes significantly less time to create a virtual disk. The thin provision format is suitable for non-IO intensive virtual machines.

Third-party plug-in framework - e.g. NetApp Virtual Console
There is no specific storage API (similar to e.g. VMwares VAAI / VASA) in RHV that utilizes array specific capabilities for virtualization purposes (e.g. offload, storage classification etc.). However RHVs REST API does allow storage specific calls. The APIs are continually being enhanced in the community.
RHV 3.2 introduced a plug-in framework (maintained with 3.5). This enables third parties to integrate new features and actions directly into the RHV Manager user interface. New menu items, panes, and dialog boxes allow users to access the new functionality the same way they use Red Hat Virtualizations native functionality. One example is the NetApp Virtual Storage Console (VSC). VSC provides integrated virtual storage management, including rapid domain provisioning and cloning of hundreds of virtual machines, while enabling Red Hat administrators to access and execute all of these capabilities using the standard RHV management interface.
RHV 3.3 introduced a Backup API can also be leveraged with array cloning & replication for DR.

Neutron Integration (Tech Preview) + various new enhancements - click for details
NEW
New in RHV 3.3. is the initial (tech preview) support for OpenStack Neutron as a network provider on Red Hat Virtualization Manager. OpenStack Neutron can provide networking capabilities for consumption by hosts and virtual machines.
The integration includes:
• Advanced engine for network configuration.
• open vSwitch distributed virtual switching support.
• Ability to centralize network configurations with Red Hat Enterprise Linux OpenStack Platform (not included).
RHV 3.4 extended the integration with Neutron as follows:
• Leverage Neutron IPAM by configuring subnets on external networks.
• Apply Neutron security groups to VM interfaces by assigning the 'SecurityGroups' custom property to relevant vNIC Profiles.
RHV 3.5 introduces a Neutron virtual appliance, to more easily get up-and-running with a Neutron server.
Also new in 3.3. are the following network features:
- simplified management network setup procedure
- New migration network role ( grant the migration role to a cluster network, separating migration data to the designated migration network, to prevent migration traffic from choking other networks)
- Virtual machine NIC-specific parameters (this enables a range of connection options, including: Create a host NIC via Mellanox UFM and connect it directly to a virtual NIC; use OpenStacks Neutron to connect a virtual NIC to one of its defined networks; pass non-standard quality of service (QoS) settings for a virtual NIC)
- Network QoS using virtual NIC profiles (users can now limit the inbound and outbound network traffic on a virtual NIC level by applying profiles which define attributes such as port mirroring, quality of service (QoS) or custom properties)
- Multiple network gateways per host (define a gateway for each logical network on a host)
- Refresh host network configuration (allows the administrator to obtain updated network configuration such as available NICs)
- Improved bond support (add new bonds from the administration portal, in addition to the five predefined bonds for each host
New in 3.4:
- Automatic propagation of network attribute changes to active hypervisors (instead of having to synchronize each host manually).
- Network labels to ease complex hypervisor networking configurations, comprising many networks.
- Predictable vNIC ordering inside guest OS for newly-created VMs.
- Hypervisors now recognize hotplugged network interfaces.
New in 3.5:
- Notifications in case of bond/NIC changing link state (e.g. link failure).
- Ability to configure custom properties on hypervisor network devices; specifically configuring advanced bridge and ethtool options.
- Support for bigger MAC address ranges.
- Dedicated network connectivity log on hypervisors to ease investigation in case of 'disaster'.
- Add a warning when unplugging a vNIC.
- Add warnings when meddling with the display network.
- Properly display arbitrarily-named hypervisor VLAN devices in the management console.
Advanced networking can also be achieved with RHEL OpenStack Platform. Starting with Red Hat Enterprise Linux 6.4, the Open vSwitch kernel module is included as an enabler for Red Hat Enterprise Linux OpenStack Platform. Open vSwitch is only supported in conjunction with Red Hat products containing the accompanying user space packages. Without theses packages, Open vSwitch will not function.

Advanced Network Switch
Details

Yes (vDS)
vSphere Distributed Switch (VDS) spans multiple vSphere hosts and aggregates networking to a centralized datacenter-wide level, simplifying overall network management (rather than managing switches on individual host level) allowing e.g. the port state/setting to follow the vm during a vMotion (Network vMotion) and facilitates various other advanced networking functions - including 3rd party virtual switch integration.
Each vCenter Server instance can support up to 128 VDSs, each VDS can manage up to 2000 hosts.

Yes
RHV 3.0 had significantly enhanced the GUI to simplify the network setup and also introduced extended bonding (NIC teaming) support that are maintained in RHV 3.1: 1) Active / Backup, 2) Load Balancing, 4) Link aggregation, 5) Adaptive transmit, Custom (Specify advanced options) - there is no Mode 3 listed
RHV 3.3 added improved bond support (add new bonds from the administration portal, in addition to the five predefined bonds for each host.
Details:
Mode 1 (active-backup policy) sets all interfaces to the backup state while one remains active. Upon failure on the active interface, a backup interface replaces it as the only active interface in the bond. The MAC address of the bond in mode 1 is visible on only one port (the network adapter), to prevent confusion for the switch. Mode 1 provides fault tolerance and is supported in Red Hat Virtualization.
Mode 2 (XOR policy) selects an interface to transmit packages to based on the result of an XOR operation on the source and destination MAC addresses multiplied by the modulo slave count. This calculation ensures that the same interface is selected for each destination MAC address used.
Mode 2 provides fault tolerance and load balancing and is supported in Red Hat Virtualization.
Mode 4 (IEEE 802.3ad policy) creates aggregation groups for which included interfaces share the speed and duplex settings. Mode 4 uses all interfaces in the active aggregation group in accordance with the IEEE 802.3ad specification and is supported in Red Hat Virtualization.
Mode 5 (adaptive transmit load balancing policy) ensures the outgoing traffic distribution is according to the load on each interface and that the current interface receives all incoming traffic. If the interface assigned to receive traffic fails, another interface is assigned the receiving role instead. Mode 5 is
supported in Red Hat Virtualization.

|
Yes (up to 32 NICs)
vSphere has integrated NIC teaming capabilities. To utilize NIC teaming, two or more network adapters must be uplinked to a virtual switch (standard or distributed).
The key advantages of NIC teaming are:
- Increased network capacity for the virtual switch hosting the team.
- Passive failover in the event one of the adapters in the team goes down
There are various NIC load balancing (e.g. based on originating port, source MAC or IP hash) and failover detection algorithms (link status, Beacon probing).
|
Yes
With RHV the Network Interfaces tab of the details pane shows VLAN information for the edited network interface. In the VLAN column newly created VLAN devices are shown, with names based on the network interface name and VLAN tag.
Background: RHV VLAN aware and able to tag and redirect VLAN traffic, however VLAN implementation requires a switch that supports VLANs.
At the switch level, ports are assigned a VLAN designation. A switch applies a VLAN tag to traffic originating from a particular port, marking the traffic as part of a VLAN, and ensures that responses carry the same VLAN tag. A VLAN can extend across multiple switches. VLAN tagged network traffic on a switch is completely undetectable except by machines connected to a port designated with the correct VLAN. A given port can be tagged into multiple VLANs, which allows traffic from multiple VLANs to be sent to a single port, to be deciphered using software on the machine that receives the traffic.

Hooks (ability to launch pre-built scripts) allow for advanced KVM technology to be supported from the Red Hat Virtualization Manager interface. Pre-built hooks include SR/IOV: Allows bypassing the hypervisor for certain network and disk I/O for near-native speed. There is no capability to configure SR-IOV devices directly through the RHV-M interface though (other than launching the hook).
Comment: Evaluated amber - as Sample scripts have been developed that include SR-IOV configuration.
Please note: The creation and use of VDSM hooks to trigger modification of virtual machines based on custom properties specified in the Administration Portal is supported on Red Hat Enterprise Linux virtualization hosts. The use of VDSM Hooks on virtualization hosts running Red Hat Virtualization Hypervisor (RHV-H) is not currently supported.

vSphere 6.x Network I/O Control (NIOC) Version 3
- Ability to reserve bandwidth at a VMNIC
- Ability to reserve bandwidth at a vSphere Distributed Switch (VDS) Portgroup
Network I/O control enables you to specify quality of service (QoS) for network traffic in your virtualized environment. NetIOC requires the use of a virtual distributed switch (vDS). It allows to prioritize network by traffic type and the creation of custom network resource pools.
|
Yes (Port Mirroring); toggle through vNIC profile
RHV 3.1 introduced port mirroring capabilities (maintained in 3.5).
It is now possible to configure the virtual Network Interface Card (vNIC) of a virtual machine to run in promiscuous mode. This allows the virtual machine to monitor all traffic to other vNICs exposed by the host on which it runs. Port mirroring copies layer 3 network traffic on given a logical network and host to a virtual interface on a virtual machine. This virtual machine can be used for network debugging and tuning, intrusion detection, and monitoring the behavior of other virtual machines on the same host and logical network.
RHV 3.3. adds the ability to create a Virtual Network Interface Controller (VNIC) profile to toggle port monitoring. There are also the vendor-supplied UI plug-ins to RHV-M, e.g. the Nagios community plugin.

Traffic Monitoring
Details
|
yes (Port Mirroring)
Port mirroring is the capability on a network switch to send a copy of network packets seen on a switch port to a network-monitoring device connected to another switch port. Port mirroring is also referred to as Switch Port Analyzer (SPAN) on Cisco switches. Distributed Switch provides a similar port mirroring capability that is available on a physical network switch. After a port mirror session is configured with a destination -a virtual machine, a vmknic or an uplink port-the Distributed Switch copies packets to the destination.
|
Yes (virtio), Mem Balloon optimization and error messages
The virtio-balloon driver allows guests to express to the hypervisor how much memory they require. The balloon driver allows the host to efficiently allocate and memory to the guest and allow free memory to be allocated to other guests and processes. Guests using the balloon driver can mark sections of the guests RAM as not in use (balloon inflation). The hypervisor can free the memory and use the memory for other host processes or other guests on that host. When the guest requires the freed memory again, the hypervisor can reallocate RAM to the guest (balloon deflation).
This includes:
- Memory balloon optimization (Users can now enable virtio-balloon for memory optimization on clusters. All virtual machines on cluster level 3.2 and higher includes a balloon device, unless specifically removed. When memory balloon optimization is set, MoM will start ballooning to allow memory overcommitment, with the limitation of the guaranteed memory size on each virtual machine.
- Ballooning error messages (When ballooning is enabled for a cluster, appropriate messages now appear in the Events tab)

Virtual Hardware version 14
VMware developed/proprietary bare-metal hypervisor, which with vSphere 5 onwards is only available as ESXi (small foot-print without Console OS). The hypervisor itself is < 150MB. Device drivers are provided with the hypervisor (not with the Console OS or dom0/parent partition as with Xen or Hyper-V technologies).
ESX is based on binary translation (full virtualization) but also uses aspects of para-virtualization (device drivers, VMware tools and the VMI interface for para-virtualization) and supports hardware assisted virtualization aspects.
|
No limit stated
The RHV Hypervisor is not limited by a fixed technology (or marketed) restriction. Red Hat lists no Limit for the maximum ratio of virtual CPUs per host.
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_Administration_Guide/chap-Overcommitting_with_KVM.html
In reality the specifications of the underlying hardware, nature of the workload in the vm and the overall restriction of 160 logical CPUs per host will determine the limit. RHV has been publicly demonstrated (see SPECvirt) to run over 550 VMs with a mix of SMP vCPU VMs showing that they can scale beyond the previously (RHV 3.0) supported 512 vCPUs per host.

DAS, iSCSI, NFS (v4), FC, FCoE, SAS, POSIX;
Virtio SCSI, GlusterFS support, online vDisk resize
NEW
RHV 3.5 added the following Storage features:
- Detaching and moving data domains, with their contained disks and associated VMs between Data Centers or even RHV setups.
- Customizing mount options for NFS domains.
RHV 3.4 added the following Storage features:
- Support for read-only VM disks.
- Mixing domains of different types (e.g. NFS and iSCSI) in a single Data Center.
RHV 3.3 added the following Storage features:
- Virtio-SCSI support (Virtio-SCSI is a new para-virtualized SCSI controller device which provides similar performance as the virtio-blk device, while improving scalability, supporting standard SCSI command sets and device naming, allowing for SCSI device passthrough)
- GlusterFS support (RHV supports native GlusterFS-based storage domains and data center types)
- Enable online virtual drive resize (Resize virtual disks while they are in use by one or more virtual machines without the need of pausing, hibernating or rebooting the guests, by specifying an Extend size by(GB) value. Disks Block Alignment scan (This feature provides a way to find the virtual disks with misaligned partitions, check if a virtual disk, the filesystem installed on it, and its underlying storage are aligned).
- Disk Hook (Adding VDSM hooking points before and after disks hot plug and hot unplug. The feature allows users to add their own functionality before hot-plugging and hot-unplugging disks).
Besides the full support for live Storage Migration RHV 3.2 added a few minor storage related functions, including the ability to perform a storage domain scan (Scan storage domain for new orphaned images and import images into storage domain) and the ability to delete VMs without deleting the virtual disks.
New in RHV 3.1 was the ability to attach any block device to a virtual machine (Direct LUN Support), the directlun VDSM hook script is no longer required perform this task. Another new feature is the ability to configure Cross Storage Domain Virtual Machines i.e. a virtual machine which has disks on multiple different storage domains. Previously all disks for a virtual machine had to be stored on the same storage domain. Support for NFS 4 had also been added.
In RHV storage is logically grouped into storage pools, which are comprised of three types of storage domains: data (vm and snap shots) , export (temporary storage repository that is used to copy and move images between data centers and RHV instances), and ISO. Although specifically mentioned, most SAS and FCoE devices are presented to the kernel in the same way and are therefore utilized by device-mapper-multipath. RHV uses device-mapper-multipath to gather available disk information so most SAS and FCoE devices are supported for use with RHV provided that the standard FC option is selected when looking for available storage in RHV.
The data storage domain is the only one required by each data center and exclusive to a single data center. Export and ISO domains are optional, but require NFS.
Storage domains are shared resources and can be implemented using NFS, iSCSI or the Fibre Channel Protocol (FCP). On NFS, all virtual disks, templates, and snapshots are simple files. On SAN (iSCSI/FCP), block devices are aggregated into a logical entity called a Volume Group (VG). This is done using the Logical Volume Manager (LVM) and presents high performance I/O.

Dynamic / Over-Commit
Details
|
Yes (Memory Ballooning)
vSphere uses several memory optimization techniques, mainly to over-commit memory and reclaim unused memory: Ballooning, memory compression and transparent page sharing. Last level of managing memory overcommit is hypervisor swapping (not desired).
When physical host memory is over-committed (e.g. the host has a total of 128GB of RAM but a total of 196GB are allocated to virtual machines), the memory balloon driver (vmmemctl) collaborates with the server to reclaim pages that are considered least valuable by the guest operating system. When memory is tight (i.e. all virtual machines are requesting their maximum memory allocation to be used), the guest operating system determines which pages to reclaim and, if necessary, swaps them to its own virtual disk.

Yes (KSM)
Kernel SamePage Merging (KSM) reduces references to memory pages from multiple identical pages to a single page reference. This helps with optimization for memory density.

Yes (Transparent Page Sharing)
vSphere uses several memory techniques: Ballooning, memory compression and transparent page sharing. Last level of managing memory overcommit is hypervisor swapping (not desired).
A good example is a scenario where several virtual machines are running instances of the same guest operating system, have the same applications or components loaded, or contain common data. In such cases, a host uses a proprietary transparent page sharing technique to securely eliminate redundant copies of memory pages. As a result, higher levels of over-commitment can be supported.
|
Yes
RHV-3.0 introduced a new feature (maintained with 3.5) called transparent huge pages, where the Linux kernel dynamically creates large memory pages (2MB versus 4KB) for virtual machines, improving performance for VMs that require them (newer OSs generations tend to benefit less from larger pages)

vCloud API
vCloud API - provides support for developers who are building interactive clients of VMware vCloud Director using a RESTful application development style.
VMware provides a comprehensive vCloud API Programming Guide. vCloud API clients and vCloud Director servers communicate over HTTP, exchanging representations of vCloud objects. These representations take the form of XML elements. You use HTTP GET requests to retrieve the current representation of an object, HTTP POST and PUT requests to create or modify an object, and HTTP DELETE requests to delete an object.
The guide is intended for software developers who are building VMware Ready Cloud Services, including interactive clients of VMware vCloud Director. The guide discusses Representational State Transfer (REST) and RESTful programming conventions, the Open Virtualization Format Specification, and VMware Virtual machine technology.

RHCI: CloudForms, OpenStack, RHV; OpenShift (Fee-Based Add-Ons)
NEW
Comment: Due to the variation in actual cloud requirements, different deployment model (private, public, hybrid) and use cases (IaaS, PaaS etc.) the matrix will only list the available products and capabilities. It will not list evaluations (green, amber, red) rather than providing the information that will help you to evaluate it for YOUR environment.
Overview:
IaaS (private and hybrid)
In July 2013 Red Hat announced Red Hat Cloud Infrastructure (RHCI) -a single-subscription offering that bundles and integrates the following products:
- RHV - Datacenter virtualization hypervisor and management for traditional (ENTERPRISE) workloads
- Cloud-enabled Workloads: RHEL OpenStack - scalable, fault-tolerant platform for developing a managed private or public cloud for CLOUD-ENABLED workloads
- Red Hat CloudForms - Cloud MANAGEMENT and ORCHESTRATION across multiple hypervisors and public cloud providers
Please find more details here - http://red.ht/1oKMZsP
PaaS:
Red Hat also offers OpenShift (PaaS), as on-promise technology as well as available as online (public cloud) offering by Red Hat. Details here - http://red.ht/1LRn7ol
There are a number of public and hybrid (on-premise or cloud) offerings that Red Hat positions as complementary like Red Hat Storage Server (scale-out storage servers both on-premise and in the Amazon Web Services public cloud). Details are here: http://red.ht/1ug7XTY

VDI Included in RHV; HTML5 support (Tech Preview)
There is one single SKU for RHV that includes server and technical workstation virtualization.
Red Hats Enterprise Virtualization includes an integrated connection broker as well as the ability to manage VDI users via external (LDAP-based) directory services. It is often referred to as RHV-D (technical workstation). The same interface is used to manage both server and technical workstation images (unlike most other solutions like e.g. VMware View, Citrix Xentechnical workstation).
Please note that VDI is an additional charge to the server product and cannot be purchased separately (i.e. without purchasing RHV for servers).
Red Hat Virtualization for technical workstations (RHV-D) consists of:
- Red Hat Hypervisor
- Red Hat Virtualization Manager (RHV-M) as centralized management console with management tools that administrators can use to create, monitor, and maintain their virtual technical workstations (same interface as for server management)
- SPICE (Simple Protocol for Independent Computing Environments) - remote rendering protocol. There is initial support for the SPICE-HTML5 console client is offered as a technology preview. This feature allows users to connect to a SPICE console from their browser using the SPICE-HTML5 client.
- Integrated connection broker-a web-based portal from which end-users can log into their virtual technical workstations
Note: VDI related capabilities are NOT listed as Fee-Based Add-Ons (no purchase of additional VDI management software is required or licenses involved to enable the VDI management capability).
However, you will require relevant client access licensing to run virtual machines with Windows OSs, see http://bit.ly/1cBdgAm for details
