What were you trying to do that didn't work?

On crashing a guest VM, there is no event 'agent-lifecycle' 'disconnected' reason: 'channel event' like expected

What is the impact of this issue to you?

https://github.com/kubevirt/kubevirt/pull/16068 : kubevirt cannot rely on the events to detect if the guest agent is still alive.

Please provide the package NVR for which the bug is seen:

I reproduced it just on recent fedora 43 on host and guest

How reproducible is this bug?:

100%

Steps to reproduce

1.  listen to libvirt events via `virsh event --all --loop`
2.  ensure via `ssh -o "StrictHostKeyChecking no" root@qemu/aivm sudo systemctl stop qemu-guest-agent` and `ssh -o "StrictHostKeyChecking no" root@qemu/aivm sudo systemctl start qemu-guest-agent` that the event reporting is like expected
3. crash the guest via `echo 1 | sudo tee /proc/sys/kernel/sysrq` and `echo c | sudo tee /proc/sysrq-trigger`

Expected results

event 'agent-lifecycle' for domain 'aivm': state: 'disconnected' reason: 'channel event'

Actual results

no event
