One would hope, but just because a customer has lots of money to spend
on hardware doesn't mean that he is rowing with both oars. This is a
supportability issue. The xen{source} folks would do themselves a
favor by trapping a guest's use of unsupported instructions and
logging it. That would make it easy enough to track down if a
customer's apps stop working when using migration.
