Actually, this is because xenstored stores data, which is
not stored on disk. Restarting is means that you restart with an empty
store, which would basically mean you can't start new domU or properly
shut down existing ones.

Also, it's not only the dom0 kernel which would need to be able to reconnect
to the xenstore, but also all domUs.
