You could use something like the monit package to monitor the domU through a variety of methods, ping, socket connect, etc. The config allows one to specify multiple rules to detect and take action based upon events.
It would be trivial to monitor a domU via ping and restart it if it stopper responding.
It's also less code you have to maintain yourself :-)

teh code, but to use an already-built mechaism for this, but i guess
none exists, so i'll modify the code for this.
Thanks!
