51 Cloning/copying, check (both "fast storage-based clone" and "full copy")
52
53 Export, check.
54
55 Move/migrate, check.

59
60 XCP is Citrix XenServer's "engine", released free a couple of months ago.
61
62 XAPI is the 'smartness' of XenServer, and thus a part of XCP

77 Gotcha :-)

79 I'm going to try out on my company's VMware boxes (the guys at
80 xen-users said that Xen runs okay on VMware, albeit without HVM domU
81 support).
