Adding an event is fairly easy, if everything you want libvirt to do is
report the event to upper layers. I volunteer to do it. Question is, how
qemu is going to report this, whether some attributes to GUEST_PANICKED
event or some new event.
I think it should be a new event, using GUEST_PANICKED could cause upper
layers to react by shutting down or rebooting the guest.
