After doing virtualization in the past with server hardware, I thought it would be fun and useful to split up my brand new PC that I built into two virtual Windows machines. I've had difficulty every step of the way, and now I'm completely stuck. I can get a single Windows VM to boot up through a RX 580 Graphics Card, but issues arise when I try to install the AMD drivers. If I try to install the AMD GPU drivers, it get's about 75% through the install and the screen flashes black and stays that way, requiring a force stop of the VM which corrupts the Windows Files and makes it freeze the next time you try to boot it up. Even if I don't do anything on the VM, the screen eventually flashes black as well, which I believe is because Windows installs the default graphics drivers after a few minutes on a new installation. This issue comes after issues with my NIC drivers, unRAID randomly freezing up (fixed with a new boot usb drive), and issues with PCIE passthrough that I have all fixed. I still get an IOMMU error when I try to pass through my other GTX 1660 Super, but that's not an issue that I'm concentrating on right now. After doing some research with the GPU driver issue, I found that some people have fixed this by using older AMD drivers, but I haven't even been able to find old drivers for the card!

 

PC Specs:

Ryzen 7 3700x CPU

Asus x570-P Prime Motherboard 

GT 710 GPU (for unRAID console)

GTX 1660 Super GPU

RX 580 GPU

Samsung 1tb SATA Drive

 

 

Any suggestions would be great. I can't come this far to fail to a driver issue, right?

Hi - I have a Ryzen 2700 host with RX 560. I was able to successfully pass it through and I had to run DDU Display Driver Uninstaller in Safe Mode to clean up what Windows installed with Windows Update.

 

Hopefully this works for you. DDU does miracles to clean up the mess in Drivers and allow a fresh install.
