There's docs/migration.txt, though I agree that we could do better
on the documentation front (some of the details are a bit subtle.

Migration proper is only really useful for KVM I think; save/restore
support (ie VM snapshots) has wider application -- I've used it for
TCG debugging sessions a few times (snapshot the system just before
it gets to the bit that falls over so you don't have to wait 5 minutes
and a lot of runtime logging to retry your failing test case).
