[Xen-users] Watchdog support in XEN?

["Andreas Bach Aaen (AH/TED)" <andreas.bach.aaen@xxxxxxxxxxxx>]

Many physical PCs have a hardware watchdog. This is a good way of getting up 
and running again if you somehow have a bug that causes a deadlock.
If you run linux in DomU you will have to use a software watchdog. The kernel 
provides such a software watchdog. But could there be scenarios where the 
DomU domain will lockup without the software watchdog goes off?
Interrupts?

So my question does XEN provide a "hardware" watchdog that the user domains 
can use?
It might be safer that the counter and trigger resides in the XEN domain than 
in the user domains.
