XenServer is supported by a number of commercial, open source and community lead projects. These projects range in scale from smaller efforts like Xen Orchestra through to major cloud orchestration solutions such as Apache CloudStack and OpenStack. In all cases, community members within those projects have invested in having XenServer be a significant player within their communities due its capabilities and breadth of install base.

Community Verified Solutions
The XenServer teams maintains a hardware compatibility list which contains all the hardware options both Citrix and the respective vendor are willing to offer support for XenServer on. The HCL is far from exhaustive, and while certification kits are available, often the reason a given piece of hardware isn't on the HCL has more to do with the vendor viewing the effort of supporting XenServer as being too costly. This is an area where your voice truly does make a difference. If you are using a given hardware component, and its not on the HCL do voice this to the vendor. Additionally, you can help your fellow users by submitting the solution as "Community Verified". Community Verified is a community lead effort within Citrix Ready organization to highlight hardware and software which has been verified as operational with Citrix products; including XenServer.
