At the moment if you try live migration on a HVM domain, it will spew
out an error saying "can't do that just yet" (not in exactly those
words, but that's the meaning of it).
But you should be able to SAVE and RESTORE a HVM domain using the
current unstable - at least once. I've got a problem with saving a
previously restored domain, but my build is a couple of days old.
Bear in mind that this is "bleeding edge" stuff, so it's definitely not
quite ready for production... ;-)
