Live Migration of VMs
Details
|
Yes
Each cluster is configured with a minimal CPU type that all hosts in that cluster must support (you specify the CPU type in the RHEV-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).
|
Yes - Live Migration
There is also a possibility to use SSL to encryption the Live Migration. More info on: http://docs.oracle.com/cd/E50245_01/index.html
|
|
|
|
Migration Compatibility
Details
|
Yes
|
Yes
On the same Cluster/Server Pool it is possible to separate the Cluster/Server Pool Members based on the CPU Family to guarantee the success of Live Migration between those Servers but there is no possibility of grouping different CPUs generations by masking out incompatible functions using CPU Masking. More info on: http://docs.oracle.com/cd/E50245_01/index.html
|
|
|
|
|
Yes - Built-in (CPU\Memory) and plugable scheduler
NEW
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. RHEV-M will use live migration to move virtual machines around the cluster as required.
A 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 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 RHEV admins to extend the scheduling process with custom python filters, weight functions and load balancing modules.
- Every cluster has a scheduling policy. 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.
|
Yes - Maintenance Mode
It is possible to execute the Maintenance Mode and It is also possible to Lock some Servers to not receive this Offload from the Server that is entering in this State. More info on: http://docs.oracle.com/cd/E50245_01/index.html
|
|
|
|
Automated Live Migration
Details
|
Yes
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 RHEV-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.
|
Yes
Oracle VM provides a DRS feature for the following constraints: (CPU-CPU, N:Network i/o) during VMs runtime and the following constraints: (CPU-CPU, N:Network i/o, MEM:Memory) during VMs startup. More info on: http://docs.oracle.com/cd/E50245_01/index.html
|
|
|
|
|
Yes
NEW
Storage Live Migration is supported and allows migration of virtual machine disks to different storage devices while the virtual machine is running. There is also an option to move an entire storage domain between datacenters or even between setups.
|
Yes

Details
|
200 hosts/cluster
That is the supported maximum number of hosts per RHEV datacenter and also per cluster (the theoretical KVM limit is higher).
|
Yes
Oracle VM provides a capability to Migrate the VM Disks to different Storage Repositories (not live). More info on: http://docs.oracle.com/cd/E50245_01/index.html
|
|
|
|
|
HA/DR |
|
|
|
|
Yes
High availability is an integrated feature of RHEV 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 RHEV-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.
RHEV-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 RHEV-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.
|
32 Hosts in Cluster/Pool
Oracle VM can have up to 32 Servers on each Clustered Server Pool and up to 64 Servers on each Unclustered Server Pool. More info on: http://docs.oracle.com/cd/E50245_01/index.html
|
|
|
|
Integrated HA (Restart vm)
Details
|
Yes (HA, WatchDog)
RHEV 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.
|
Yes - Clustered Pool
Oracle VM will restart HA-enabled Guests on remaining Hosts in case of Host failure. More info on: http://docs.oracle.com/cd/E50245_01/index.html
|
|
|
|
Automatic VM Reset
Details
|
No
There is no live lock-step mirroring support in RHEV - although the theoretical capability is available in KVM. Red Hat tends to points out that the limitations around this technology (inability to take e.g. snap shots, perform a live storage migrate, limited guest vCPU support, high bandwidth/processing requirements) can make it inappropriate for enterprise implementation.
|
Yes
Oracle VM will restart Guests on the same Host due to OS Failures. More info on: http://docs.oracle.com/cd/E50245_01/index.html

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.
- Host network QoS can define limits on network usage on the pysical NIC.

User Portal
RHEVs web-based Power User Portal is positioned by Red Hat as an entry-level Infrastructure as a Service (IaaS) user portal.
It allows the user to: create, edit and remove virtual machines, manage virtual disks and network interfaces, assign user permissions to virtual machines, create and use templates to rapidly deploy virtual machines, monitor resource usage and high-severity events, create and use snapshots to restore virtual machines to a previous state. In conjunction with the quota functionality in RHEV administrators can restrict resources consumed by the users (but there is no integrated request approval or granular resource assignment based on e.g. subsets of the resources through private clouds).

sVirt, SELinux, iptables, VLANs, Port Mirroring
The RHEV 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).
Advanced network security features like VLAN tagging and port mirroring are part of RHEV, but there are no additional security-specific add-ons included with RHEV (e.g. to address advanced fire-walling, edge security capabilities or Anti-Virus APIs).

RAW, Qcow2
RHEV 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).
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. The thin provision format is suitable for non-IO intensive virtual machines.
|
Yes
Technically is possible but not officialy supported by Oracle. More info on: http://docs.oracle.com/cd/E50245_01/index.html

Virtual Disk Format
Details
|
Default max virtual disk size is 8TB (but its configurable in RHEV DB)
The default maximum supported virtual disk size is 8TB in RHEV (but its configurable in RHEV DB).
With virtio-scsi support, Red Hat also supports now 16384 logical units per target.
File level disk size remains unlimited by the hypervisor, the limits of the underlying filesystem do however apply.
|
Raw Images (*.img files)
If a disk is created from OVM Manager it is created by default as a Raw image and if it is imported it is converted from the original format to Raw Images. More info on: http://docs.oracle.com/cd/E50245_01/index.html
|
|
|
|
|
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.
|
10 TB (Virtual Disk on OCFS2), Maximum supported on the Guest OS (Raw Disks)
For NFS there is no limit specified since it depends on the Backend Local Filesystem of the NFS Server. More info on: http://docs.oracle.com/cd/E50245_01/index.html

|
|
|
|
|
Yes
In RHEV 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.

Advanced Network Switch
Details
|
Yes
RHEV support 4 bonding modes with easy management of their definition on the 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 Enterprise 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 Enterprise 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 Enterprise 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 Enterprise Virtualization.

With RHEV 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: RHEV VLAN is aware and is 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.

RHEV has port mirroring capabilities.
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.
RHEV also 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 RHEV-M, e.g. the Nagios community plugin.

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)

DAS, iSCSI, NFS, GlusterFS, FC, POSIX;
Virtio SCSI support
RHEV storage is logically grouped into storage pools, which are comprised of three types of storage domains: data (vm and snapshots) , export (temporary storage repository that is used to copy and move images between data centers and RHEV instances), and ISO.
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 or POSIX.
Storage domains are shared resources and can be implemented using NFS, GlusterFS, POSIX, 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.
Luns can be directly attached to VMs as disks, but some feature are not supported when this option is used like snapshotting.
Local storage can be used to create non-shared local datacenter which allow a single host.

REST API, Python CLI, Hooks, SDK
RHEV exposes several interfaces for interacting with the virtualization environment. These interfaces are in addition to the user interfaces provided by the
Red Hat Enterprise Virtualization Manager Administration, User, and Reports Portals. Some of the interfaces are supported only for read access or only when it has been explicitly requested by Red Hat Support.
Supported Interfaces (Read and Write Access):
- Representational State Transfer (REST) API: With the release of RHEV-3 Red Hat introduced a new Representational State Transfer (REST) API. The REST API is useful for developers and administrators who aim to integrate the functionality of a Red Hat Enterprise Virtualization environment with custom scripts or external applications that access the API via standard HTTP. The REST API exposed by the Red Hat Enterprise Virtualization Manager is a fully supported interface for interacting with Red Hat Enterprise Virtualization Manager.
- Python Software Development Kit (SDK): This SDK provides Python libraries for interacting with the REST API. The Python SDK provided by the rhevm-sdk-python package is a fully supported interface for interacting with Red Hat Enterprise Virtualization Manager.
- Java Software Development Kit (SDK): This SDK provides Java libraries for interacting with the REST API. The Java SDK provided by the rhevm-sdk-java package is a fully supported interface for interacting with Red Hat Enterprise Virtualization Manager.
- Linux Command Line Shell: The command line shell provided by the rhevm-cli package is a fully supported interface for interacting with the Red Hat Enterprise Virtualization Manager.
- VDSM Hooks: 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 Enterprise Virtualization Hypervisor is not currently supported.
Additional Supported Interfaces (Read Access)
Use of these interfaces for write access is not supported unless explicitly requested by Red Hat Support:
- Red Hat Enterprise Virtualization Manager History Database
- Libvirt on Virtualization Hosts
Unsupported Interfaces
Direct interaction with these interfaces is not supported unless your use of them is explicitly requested by Red Hat Support:

RHCI: CloudForms, OpenStack, RHEV; Satelite, 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)
Red Hat offers Red Hat Cloud Infrastructure (RHCI) -a single-subscription offering that bundles and integrates the following products:
- RHEV - 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
- Red Hat Satellite - A system management platform that provides lifecycle management for Red Hat
Enterprise Linux for both host and tenant operating systems within Red Hat Cloud Infrastructure.

VDI Included in RHEV; HTML5 support (Tech Preview)
There is one single SKU for RHEV that includes server and desktop 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. The same interface is used to manage both server and desktop images (unlike most other solutions like e.g. VMware View, Citrix XenDesktop).
Please note that VDI is an additional charge to the server product and cannot be purchased separately (i.e. without purchasing RHEV for servers).
Red Hat Enterprise Virtualization for Desktops (RHEV-D) consists of:
- Red Hat Hypervisor
- Red Hat Enterprise Virtualization Manager (RHEV-M) as centralized management console with management tools that administrators can use to create, monitor, and maintain their virtual desktops (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 desktops
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
