Comment 5 for bug 1246626

For shutdown, could MAAS in many situations be able to ssh into the host and power it off? It would not work on hung systems or for custom images, but could work in general cases.

Power status could be the same, with either an agent on the host, or pinging the knows address MAAS knows about. It would not catch all cases (hosts that firewall UDP, etc.), but it would work for most cases.
