Ok. So for the first implementation of sync_manager it will still be
possible for someone to corrupt data by configuring two separate vms to
accidentally use the same storage volumes. That's fine for the first
pass, just something to keep in mind for later.
(That's slightly misleading; technically, the lock prevents a
second qemu
process from even being started.)
