[alex.tls]

Hi team,

I found my windows VM always was stop by somehow, I guess it is caused by RAM exhaustion or other problem in my proxmox.

but how to verify that , is there any log record that ?

Hi. Check if the machine as scsi adapter on it. If yes, change to virtio-blk and test again.

If the VM is still running, is may not be a PVE problem, but a Windows problem. Check the Windows logs and do internal Windows memory dumps to get the error.
You can also disable memory ballooning and try again.

Hi @LnxBil, that VM is totally stop, that why I want to find some clue within PVE.

Exists a bug on 7.4 when Windows use Virtio SCSI. If you read on Events you will see 129 Event.

maybe it has something to do with the power setting in my windows VM, let me try to disable fastboot and hibernate.

I see this kind of log in my VM

Don't use hibernate or other power saving techniques in VMs, this produces very strange errors.

working well in these days after I disable hibernate.
