Was there any consensus reached in this thread? I'm once again looking
for ways to communicate qemu watchdog events to libvirt.
With these patches, libvirt could open a second monitor connection to
qemu, and in the second one execute "wait_event". When the watchdog
triggers, the wait command would print the event, libvirt would get the
fd "data available" notification, and create a domain event. Right?
