I think the difference in events, while annoying, is the right thing to have, becasue the fact that QEMU is shutoff & re-spawned can have implications for integration into the system & thus should be reflected. To make it slightly nicer though, we should make sure that the lifecycle event "reason" detail, reports "REBOOTED" as the cause. That would let control plane software understand that these events are from a fake reboot.
