I can't get the mentioned combination get to work.
I installed the
vioserial driver in the guest, installed the Guest Agent and added the Qemu Guest Agent channel to the VM.
Both guest services are running.
I checked the permissions in
Still, the "Fit resolution" option under "View" is greyed out with the tooltip "No connection to guest agent".
Host is Debian stable, guests are Windows 7 Pro and Windows 10 Pro (x64). Any idea?
