Thread-topic: [Xen-API] Create a Virtual machine with a specific UUID
xe is for both XenServer and XCP.

I think that using the XenAPI against xend is probably inadvisable - I believe 
that it's not well maintained at the moment. Your best options are really to 
use xl on Xen 4.0, or XenAPI against XCP/XenServer.
