Fix by uninstall

In Proxmox VE, the qemu-guest-agent is used for mainly two things:

  • To properly shutdown the guest, instead of relying on ACPI commands or windows policies
  • To freeze the guest file system when making a backup (on windows, use the volume shadow copy service VSS).

If uninstall as the permanent solution, make sure that untick the Use QEMU Guest Agent under VM options.
