Yes (XenCenter), SCVMM (see details)
XenCenter is the central Windows-based multi-server management application (client) for XenServer hosts (including the open source version).
It is different to other management apps (e.g. SCVMM or vCenter) which typically have a management server/management client architecture where the management server holds centralized configuration information (typically in a 3rd party DB). Unlike these management consoles, XenCenter distributes management data across XenServer servers (hosts) in a resource pool to ensure there is no single point of management failure. If a management server (host) should fail, any other server in the pool can take over the management role. XenCenter is essentially only the client.
License administration is done using a separate web interface.
XenServer 6 introduced the ability to manage XenServer hosts and VMs with System Center Virtual Machine Manager (SCVMM) 2012. System Center Operations Manager (SCOM) 2012 will also be able to manage and monitor XenServer hosts and VMs. System Center integration is available with a special supplemental pack from Citrix.
Citrix announced with v 6.2 that several features will not be further developed and will be removed in a later release. These deprecated features function as in XenServer 6.1.0 and will remain supported, providing a period of overlap while third-party products or alternative solutions are established.
WLB has returned to XenServer 6.5 (Enterprise Edition) having been retired with the launch of XenServer 6.2. The deprecation notice for DVSC has also been rescinded within XenServer 6.5.
This initially included: Microsoft System Center Virtual Machine Manager (SCVMM) support
However, Citrix confirmed: Citrix is not deprecating support for SCVMM. However, SCVMM 2012 R2 does not currently support XS 6.2 (this being a Microsoft decision), because XS 6.2 was not released in time for this to happen).

Limited (plug-ins)
vCenter and associated components focus on management of virtual infrastructure - physical (non-virtualized) infrastructure will typically require separate management.
However, one can argue that there are increasingly aspects of physical management (bare metal host deploy, vCenter Operations capabilities, vCenter monitoring of physical hosts etc. but the core focusses on the virtual aspects).
Additionally, VMware encourages 3rd party vendors to provide management plug-ins for the vCenter Client (classic or web) that can manage peripheral components of the environment (3rd party storage, servers etc.).

Yes (hosts/XenCenter)
XenServer 5.6 introduced Role Based Access Control by allowing the mapping of a user (or a group of users) to defined roles (a named set of permissions), which in turn have the ability to perform certain operations. RBAC depends on Active Directory for authentication services. Specifically, XenServer keeps a list of authorized users based on Active Directory user and group accounts. As a result, you must join the pool to the domain and add Active Directory accounts before you can assign roles.
There are 6 default roles: Pool Admin, Pool Operator, VM Power Admin, VM Admin, VM Operator and Read Only - which can be listed and modified using the xe CLI.

Additional Info:
XenServers Integration Suite Supplemental Pack allows inter-operation with Microsofts System Center Virtual Machine Manager 2012 (SCVMM) and Systems Center Operations Manager (SCOM). SCOM enables monitoring of host performance when installed on a XenServer host.
Both of these tools can be integrated with your XenServer pool by installing the Integration Suite Supplemental Pack on each of your XenServer hosts.
For virtual desktop environments Citrix EdgeSight is a performance and availability management solution for XenDesktop, XenApp and endpoint systems. EdgeSight monitors applications, devices, sessions, license usage, and the network in real time, allowing users to quickly analyze, resolve, and proactively prevent problems.

The XenCenter released with XenServer 6.5 allows updates to be applied to all versions of XenServer (commercial and free)
With XenServer 6.5 patching and updating via the XenCenter management console (enabling automated GUI driven patch application and upgrades) is supported with the comercial and free XenServer versions.
XenServer 6 introduced the Rolling Pool Upgrade Wizard. The Wizard simplifies upgrades to XenServer 6.x by performing pre-checks with a step-by-step process that blocks unsupported upgrades. You can choose between automated or semi-automated, where automated can use a network based XenServer update repository (which you have to create) while semi-automated requires local install media. There are still manual steps required for both approaches and no scheduling functionality or online repository is integrated.

No (Retired)
Citrix retired the Virtual Machine Protection and Recovery (VMPR) in XenServer 6.2. VMPR was the method of backing up snapshots as Virtual Appliances.
Alternative backup products are available from Quadric Software, SEP, and PHD Virtual
Background:
With XenServer 6, VM Protection and Recovery (VMPR) became available for Advanced, Enterprise and Platinum Edition customers.
XenServer 5.6 SP1 introduced a basic XenCenter-based backup and restore facility, the VM Protection and Recovery (VMPR) which provides a simple backup and restore utility for your
critical vims. Regular scheduled snapshots are taken automatically and can be used to restore VMs in case of disaster. Scheduled snapshots can also be automatically archived to a remote CIFS or NFS share, providing an additional level of security.
Additionally the XenServer API allows for scripting of snapshots. You can also (manually or script) export and import virtual machines for backup purposes.

Yes
Templates in XenServer are either the included pre-configured empty virtual machines which require an OS install (a shell with appropriate settings for the guest OS) or you can convert an installed (and e.g. sysprep-ed) VM into a custom template.
There is no integrated customization of the guest available, i.e. you need to sysprep manually.
You can NOT convert a template back into a VM for easy updates. You deploy a VM from template using a full copy or a fast clone using copy on write.

vApp is a collection of virtual machines (VMs) and sometimes other vApps that host a multi-tier application, its policies and service levels.

|

vApp
XenServer 6 introduced vApps - maintained with v 6.5
A vApp is logical group of one or more related Virtual Machines (VMs) which can be started up as a single entity in the event of a disaster.
The primary functionality of a XenServer vApp is to start the VMs contained within the vApp in a user predefined order, to allow VMs which depend upon one another to be automatically sequenced. This means that an administrator no longer has to manually sequence the startup of dependent VMs should a whole service require restarting (for instance in the case of a software update). The VMs within the vApp do not have to reside on one host and will be distributed within a pool using the normal rules.
This also means that the XenServer vApp has a more basic capability than e.g. VMwares vApp or MSs Service Templates which contain more advanced functions.

Yes (Storage Based Policy Management)
Using the Storage Based Policy Management (SPBM) framework, administrators can define different policies with different IO limits, and then assign VMs to those policies. This simplifies the ability to offer varying tiers of storage services and provides the ability to validate policy compliance.
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.

Yes
vSphere supports hierarchical resource pools (parent and child pools) for CPU and memory resources on individual hosts and across hosts in a cluster. They allow for resource isolation and sharing between pools and for access delegation of resources in a cluster. Please note that DRS must be enabled for resource pool functionality if hosts are in a cluster. If DRS is not enabled the hosts must be moved out of the cluster for (local) resource pools to work.

A resource pool in XenServer is hierarchically the equivalent of a vSphere or Hyper-V cluster. There is no functionality to sub-divide resources within a pool.
