Hello All,
I have been piecing together a few different guides on setting up a VM for GPU pass through. My main machine is on Fedora 31. VM to Windows 10 and connected to another input on my main display.
I have been trying to setup Looking Glass after I spent a few days making sure the VM was working. I have the client for Release/B1 running but it only displays a Purple screen. I have tried to run the Host application through Task Scheduler and manually with Run as Administrator and nothing happens.
Here is the config file for my vm and the looking-glass-host.txt log file form the Host application
