Ok, so you have the domain in the xenstore on hyp10 and not in
the xenstore on hyp11, you run the live migrate and it gets the
error. Do I have that right?
If the domain is in hyp11, delete it, otherwise they will
collide on migration. You can only have 1 resource with a
given UUID defined per-hypervisor.
