Excellant, although we still need to use the 'kill' approach for any VMs
which don't support the 'system_powerdown' monitor command. We should
probably try 'system_powerdown' and if that gets rejected then fallback
to just killing it. Figuring out if its rejected could be fun though;
Would have to look at the returned 'info' for an error message - hopefully
QEMU has one.
