Maxime Courtemanche Posted February 19 Share Posted February 19 I followed Spaceinvader One guide to get the video card to passthrough the VM. When I start the VM I don't get any output from the video card. Any help would be appreciated. And I did the VFIO configuration for the Nvidia card. lrwxrwxrwx 1 root root 0 Feb 19 20:06 0000:40:01.0 -> ../../../../devices/pci0000:40/0000:40:01.0 lrwxrwxrwx 1 root root 0 Feb 19 20:06
