Hypervisor support matrix
This is an attempt to help new users decide on a hypervisor based on features that can be controlled through compute.
Most OpenStack development is done with the KVM and XEN hypervisors. This means that (currently at least) you are more likely to find community support for issues with these hypervisors. All features that are currently supported in KVM are also supported in QEMU.
As far as the Xen hypervisor is concerned, it is worth noting the following definitions:
- XenServer: Commercial, supported product from Citrix.
- Xen Cloud Platform (XCP): Open-source equivalent of XenServer (and the development project for the toolstack). Everything said about XenServer below applies equally to XCP.
- XenAPI: The management API exposed by XenServer and XCP.
- XAPI: The primary daemon on XenServer and Xen Cloud Platform; the one that exposes the XenAPI.
Nova has support for XenServer and XCP through the XenAPI virt layer. Note that this does not imply support for other Xen-based platforms such as those shipped with RHEL 6 or SUSE, which is provided via the libvirt layer.
Please help keep this list up-to-date.
Legend: ✔ indicates support, ✗ indicates the feature is not supported, G indicates the feature will be added in Grizzly, * indicates there is a caveat to the functionality (caveats need to be documented!), and a blank cell generally indicates more testing is needed to make a judgment.

- Inject Networking only works with nova-network in Flat mode, and only with Debian/Ubuntu based virtual machines, and only at boot time
- XenServer integration also supports using a guest agent to inject networking settings, at any time when a VM has the guest agent installed, through an admin API extension
- XenAPI Config drive support was added in Grizzly
- XenAPI support for serial console is currently under development
- Unknown: VNC support has since been unified between libvirt and XenAPI
- Functionality provided by cloudbase-init for windows http://www.cloudbase.it/cloud-init-for-windows-instances/
- Vlan and Routing is supported on Hyper-V when using the Quantum Hyper-V Plugin
- Support of Xen using Libvirt
Description of features
The `nova diagnostics` command will provide some information about resource use associated with an instance. See the OpenStack Compute admin guide for more details.
Auto configure disk
Automatically reconfigure the size of the partition to match the size of the flavor's root drive before booting.
