Hi there!

I had this issue multiple times now and just want to find out whats going on. When i log into my proxmox host I see an unusual load on my node and several VMs had stopped. I can not start them again because the kvm (id 504) is still running with a high cpu load (see screenshot). An other VM (501) just stopped without any process still running.

Is there any way to find out in a logfile what happened here? It happened with oder VMs too. So it's not just that two VMs with the problem.

Thanks in advance!

what does 'qm status 504 --verbose' say in this state?
check the syslog (/var/log/syslog or journalctl) and search for that vmid (504)

are there any .pid files in /var/run/qemu-server?
if yes, do the pids inside match with the running processes?

For my 501 machine (also stopped but without a process still running or a log entry) there is no PID file. The 504 has a PID which do not match the processes.

ok it seems the main qemu process died somehow (13072) but the childs still run (13073)

you could try to run the vm in the foreground ('qm showcmd ID' gives the qemu commandline and from that remove the '--daemonize' flag to run in foreground)
to see why it dies/get killed if nothing in the log is found...

So you mean i kill the process right now, restart it in the foreground and just wait for the next crash? Thank you for the help btw :)

yes this is what i meant, but only if the logs do not tell you anything else
is the vm still working btw? maybe you can shut it down from ssh or something like that? (instead of killing it)

No it's not reachable. I also tried it over my internal switch only > no route to host
Nothing helpful in the logs so far. Is there anyway to increase the loglevel maybe?
