Xen / XCP / XAPI Overview

Icon Info.png NOTE: XCP is deprecated. It was the open source equivalent to XenServer, but now XenServer is open source as well. People interested in XCP should be exploring the open source XenServer instead, as XCP is no longer updated. For Xenserver, go to xenserver.org.
