I'm curious why you want that. The Xen migration system is designed to
make the migration basically seamless (and as I mentioned before, pauses
the domain momentarily to achieve this). You already need shared storage
to do migration (unless you're using Remus, which is a whole nother
ballgame), so why block IO?
