Note that the order has swapped. If these aren't consistent we don't
have a good way to determine which host devices map to which guest devices.
This is not good.
Ideas?
qemu -drive has a serial=... option. I'm not clear what it does, but
if there is a way to assign a UUID to the device on the host side, and
read that from the guest then we should be able to restore the
ordering.
