Subject: [PATCH] spice: notify spice server on vm start/stop

Spice server needs to know about the vm state in order to prevent

attempts to write to devices when they are stopped, mainly during

the non-live stage of migration.

Instead, spice will take care of restoring this writes, on the migration

target side, after migration completes.
