QM running (internal-error)

Hello,
after years of running on proxmox, I've experienced from yesterday issue with one of my VM's which stopped responding.
It showed "running (internal-error) on the UI

whole pvestatsd needed to be restarted in order to see statuses of the remaining VM's (but that might be side effect).
when performing backup to the Proxmox Backup server Host completely frozen.
I've disabled backup and host is now running even when that given VM is in internal error.

no clue what happened. Found this in the syslog, can somebody please help me decode what that means?
Host has microcode installed and been running fine for long time.

Thanks a lot

Hi,
please share the output of pveversion -v and the VM configuration qm config <ID> --current. If the issue occurs again, you might want to try booting an older kernel to see if that makes a difference.
 
Thanks for the reply
here it is.

this is actual frozen issue syslog:

This time it looks bit different in the syslog

Might be issue with kernel? how to safely install older one back? (asking for friend :) )

Hmm, those messages are quite different then the first one you posted. Might point to hardware issues. I suggest you check your memory with e.g. memtest86+ which can be started from the Proxmox VE installer ISO.
 
I have exact same hw with same proxmox, so I've migrated everyhting and that problematic instance will now run without any VM's to narrow down the issue.
Also I have cluster running, so I have options.
I did memcheck and diskcheck couple of times, all results been OK, which does not telling anything it cannot be wrong indeed :)

I've seen similar iissue recently in this forum, which hasn't been solved yet ... so who knows

What host CPU do you have? Are the latest CPU microcode and BIOS updates installed?

That one is a bit of a different error though:
KVM internal error. Suberror: 3
instead of your
error: kvm run failed Invalid argument
and the host didn't freeze.
 
Yes I do have microcode installed (latest).
Bit of the update: when running without any VM's it's not freezing of course. Did another memtest, and everything went OK.

I'm bit clueless for now actually
 
You can still test with an older kernel. It could be a regression there.
 
so bit of update, node itself (without any VM's) running 2days without an issue. So I guess I need somehow debug if some exact VM is causing issue, or any.
Is there some sort of debug which I can use ? as in syslog there is nothing more and on VM there is nothing really.

This error in the system logs does include the PID (i.e. 1564) of the QEMU process:
Code:
Sep 29 04:15:42 inception QEMU[1564]: error: kvm run failed Invalid argument
You can use qm list or to see which VM ID it belongs to next time the issue happens.
