How does the VM-config look like? (qm config YourVMID)
Did you follow: [1] and installed all drivers?

EOL since over two years: [2] (PVE 6 is also EOL.)

Thank you all for your support
This was all that was necessary from the wiki steps, and fixed all my problems too, including memory usage not being reported accurately;


The easiest way to install missing drivers and services is to use the provided MSI installer. It is available on the driver CD since version "virtio-win-0.1.173-2".

Run the "virtio-win-gt-x64.msi" file located directly on the CD. If you do not plan to use SPICE you can deselect the "Qxl" and "Spice" features. Restart the VM after the installer is done.
