Citrix XenServer: Product Editions and Licencing

The features included in XenServer vary by product edition. Even the free version is enterprise-ready. From XenServer 6.5 onwards, many features which were previously in the high-end editions (such as Site Recovery and Distributed Virtual Switching) are now included even in the free version The free version can be upgraded to one of the premium editions just by purchasing a licence and pointing your XenServers at a licence server with this licence on. No reinstallation is required.

Licencing is simply done on a per-socket basis. There is no need to purchase licences to gain central management of all your XenServers.
