Hi,

i am on an enterprise subscription of proxmox 6.0 and have the latest packages installed. Since a couple of days some of the backups will not be performed correctly:

This does not happen for all VMs, but some of them. While trying to reboot the VMs, i noticed that they also cannot be gracefully shutdown. This will result in:
Code:
TASK ERROR: VM quit/powerdown failed
Any idea what might cause this?

The Setup of the VMs is quite standard (some on lvm, some as qcow as seen above) and there is only 1 VM instance running in this case.

Sebastian
 
No VNC does not work either and the shutdown works after a hard reset, the issue description matches with the issue you mentioned, so i will try to gather some debug logging for you :)
