Hi Folks,
relative newbie here.
Thanks for all the work which has gone into this. It's an amazing tech.
I am running a win10 guest on an Ubuntu 20.04 hypervisor. It is passing
through a Radeon RX560 and a Fresco USB. Also passing through the Realtek
sound controller. It runs from an SSD block device. I've done some tuning
of the CPUs for better response and you cannot tell that it's a VM.
Well.. there is one problem. It will never shutdown its screens. The host
will shutdown its screen but the guest never figures out that it needs to.
My guess is that the idle detection in the guest is not working correctly.
Is there anything I can do?
Attached is my VM's XML.
Thanks!!!
