If it was initiated by libvirt itself, I guess we can fire it after we
suddenly miss the domain. Destroy would be a direct miss that isn't marked
as crashed. (directly leads to the question: does libvirt clean up crashed
states?)
In the absence of this support in libvirt you can infer events by
periodically
sampling virDomainGetInfo and tracking changes in the state - though of
course you can miss some intermediate states. This is what virt-manager does
for event tracking.
I was thinking about implementing this TODO...
With a brainstorm session within our group I also pointed out it would be
pretty hard to find a 'within domain' initialised reboot/shutdown. Do you
have any clues on that one?
