This is a simple and easy guide to setting up a laptop for GPU passthrough.
After doing this my GPU is no longer recignised by my system help
Hi. Thank you for this repository. After doing all the steps you said, the driver was not installed. I added "sub-vendor-id" and "device-id" values to the xml file and the driver was installed, but this time the video card was not active because it gave code 43 error.
Here my vm xml:
