Watchdog event is very important for high reliability. It can tell 
what's wrong on the guest.

I'm  considering a new patch after this patch was merged. It can support 
a new API or channel to notify the watchdog event to the engine.

Seems there is not an asynchronous event channel for engine.

Maybe a new API for the engine.  Engine can poll it to check the 
watchdog event.

I will discuss it on the ovirt IRC channel  with the engine expert.


Currently, we do not have any plans to implement the engine side of the 
feature.
But I will add a watchdog feature page to describe how engine enable 
this feature. It's definitely great if any engine guy would like to take 
the engine part. I will be glad to provide help if needed.
