I have an ASUS Zephyrus G15 Laptop with an AMD iGPU and NVIDIA dGPU. It’s running Fedora 34 and uses GPU pass-through of the NVIDIA dGPU to run Windows 10 guest for gaming and other things. I am using Virtio drivers as well. Output config in my XML is through the usb-c port that is connected to the dGPU. So I use a USB-C to HDMI adapter to connect to an external HDMI display and it seems to work pretty well.
However, I also want to be able to be able to view the output from the guest OS on my Fedora host through a window, but I want to preserve most of the performance I am getting with the external HDMI display. Can I achieve this with the Spice monitor somehow? Or will I get better results with Looking Glass?
Right now, my setup is such that the output goes to external monitor and requires a separate keyboard and mouse from the one used on the host.
With Looking Glass, will I be able to use the same keyboard and mouse as host?
Secondly, what are the latest install and setup directions, and are there any for Fedora 34?
