Hi Doron,

I have updated the wiki page. 
http://wiki.ovirt.org/wiki/Add_an_option_to_create_a_watchdog_device
And for vdsm side, I should also add a new patch to report the watchdog 
event.

I can add a flat to vm's status, so engine can poll vm's status to check 
the event then notify the user, and let the user to take some actions, 
such as restart or dump guest for analysis.
Perhaps event report channel is more better, but I have not find any in 
vdsm.  But it is a big work to add an event register mechanism for vdsm.

what's your suggestion?
