There are a set of config options to choose what to do on various guest
state transitions. I think these are probably what you're looking for. See
the final bit of tools/example/xmexample1.

Hmmm... Actually it may be that we unconditionally kill the domain if it
ignores shutdown. If that is the case, we should instead force it into
whatever the the target of the 'sm shutdown' command was, and then execute
the action specified in the config file. We'd like a patch if this is the
case. :-)
