I have similar question on the fixed-ram work, on whether we should assume
the vm stopped before doing so.  Again, it leaves us space for
optimizations on top without breaking anyone.

The other thing is considering a very busy guest, migration may not even
converge for "file:" URI (the same to other URIs) but I think that doesn't
make much sense to not converge for a "file:" URI.  The user might be very
confused too.
