If the device goes into a broken state, it should be discoverable from outside. I'm not sure we need an actual event signalling this if this happens due to the guest doing something wrong: That would be a task for tools monitoring _inside_ the guest. For tools monitoring the health of the machine (from the host perspective), the discovery interface would probably be enough?
