Very strange .. I just tried the same, albeit with the KVM backend, and
it works fine. The two UUID's are the same, both if the XML used to
define it has an explicit UUID, and if it is assigned in the backend.

I don't have a Xen host set up right now, so it's probably a silly
question: Does Xen assign UUID's when domains are defined, or only once
a domain is created ?
