Guest powered off after snapshot backup

[Valerio Pachera]

The 13th March 23:30 proxmox started doing vm backup.
This morning I found the the guest id 100 powered off.
I noticed the message 'VM is locked'.



In /var/log/messages I see

grep ' qm' /var/log/messages

Hi,

Please update to the current version, your version is over 2 Years old.

Right now, I can't update that server.
I tried to backup a single guest each day and only a one guest is giving the lock problem (a windows 2012).
Note: this is the only windows guest with qemu-ga.
Because this is a production server, I can't do much testing.
Do you think the issue may be related to qemu-ga?
Or is there any log I can check to get more info?

Thank you.

No qga will skipped if do not work proper.
I think it is an windows driver problem.
Can you send the VM config of this VM?
