xl3b4n0nx Posted February 9, 2020 Share Posted February 9, 2020 I am trying to setup a Ubuntu VM with a Nvidia GPU passed through. The GPU is not the primary GPU in the system so passthrough shouldn't be an issue. I am running a Threadripper 1920X on the AsRock X399 Fatal1ty Professional Gaming. The GPUs in the system are Quadro K4000 (primary), GT 730, Quadro K2000. I am trying to pass through the Quadro K2000. When I start the VM the VM and docker managers hang then the whole system hangs. A clean shutdown is not possible. The error in the system log is libvirtd tainted and then a stack trace which clearly indicates the GPU is the problem. For reference, I have other VM's running without GPUs with no issue at all. UnRAID Nvidia version 6.8.2. Diagnostics are attached. VM settings: CPU Mode: Host Passthrough Machine: Q35-4.2 USB Controller: 2.0 GPU 1: VNC GPU 2: Quadro K2000 Sound Card: Quadro audio tower-diagnostics-20200209-1621.zip Quote Link to comment

It has never worked that way for me. If you want remote access, Ubuntu has its own screenshare (which is essentially VNC server) or you can install other solutions e.g. NoMachine using VNC first. Then change VNC to the GPU. Quote Link to comment
