[Ussuri] Auto shutdown VM


Hello Eugen 

Thanks for the response. I am pretty sure none was playing with virt-manager. Wil check libvirt logs and update back. 

Even enabled crashdump in vm which didnâ??t generate any at the time of vm shutdown.

In qemu logs there was just one message stating â?? 2020-11-13 07:00:52.164+0000: shutting down, reason=crashedâ??

And since nova has to catch up at some point this led to a cycle of unwanted shutdown events. In my case I know that users were trying to do that via virt-manager, does that apply to your scenario, too? Or does libvirt show any error logs that would explain unexpected shutdowns?
