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 feature 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, F indicates the feature will be added in Folsom, * 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.
