Using xl, not currently AFAIK.

I can see how this might be useful though, so it's is something we could
consider for 4.5, patches welcomed. I'd think that stashing the setting
in xenstore and providing a command to change it, with the attendant
watches in the xl monitoring daemon would be the way to go.

It might also be useful to have a mechanism to have xl start monitoring
a domain which it didn't just create, which would allow the daemon to be
restarted e.g. on upgrade.
