kennelm Posted May 5, 2018 Share Posted May 5, 2018 (edited) Thanks to the help received from user 1812, I got my new GT-710 to successfully pass video through to a guest VM running EL7. After I declared premature victory on this, I realized that what I really want is to make the video passthrough work while running the proprietary NVIDIA driver on the guest VM (Initially, it was the default Nouveau? driver I think). The reason I want the NVIDIA driver is for VDPAU decoding of HD encoded content on the guest VM, but I digress. So, I set about getting the NVIDIA driver installed on the guest VM, which succeeded. I've done this plenty of times on physical machines, but never on a VM. Anyway, when I boot the VM using VNC, the desktop launches correctly and, according to the logs (Xorg.0.log), the NVIDIA driver was loaded and working. Schwing. Problem is, if I boot the VM with passthrough of the GT-710 instead of VNC (with the same NVIDIA driver configuration in effect), the desktop never launches. I forced a recreate of the xorg.conf file using nvidia-xconfig (oddly, VNC launches successfully with no xorg.conf in place), but that still didn't work. All I get is a garbled screen on a Samsung 32" LCD TV. Log files and config files attached. Any thoughts or advice appreciated. I will point out that I am not doing anything with ROM passthrough, and I'm not really sure this is required, or if this is just a performance optimization for gaming, etc. I have 2 video cards on the host machine: the onboard for unraid itself and the GT-710 for the guest VM.
