Hi all, I'm hoping someone can help me.
Hardware specs:
- ASUS P8B WS
- Xeon E3-1230 v2
- 10GB ECC RAM
- Haupagge WinTV QuadHD (TV Tuner)
- Nvidia Quadro P400
VM: Ubuntu Server 20.04 LTS
What I was hoping to do was use PCI/GPU passthrough to pass through the GPU and TV Tuner to a Ubuntu server running Plex media server. I was able to get the TV tuner working and it could scan channels, etc, and the GPU was also detected by Ubuntu, however no matter what I did I could not get the latest Nvidia drivers working and some of the hardware details aren't complete.
I tried installing from the official Ubuntu PPA, the Nvidia PPA, I tried upgrading Ubuntu to the latest release 21.10. I tried 21.04. I tried the 20.04 LTS version. I tried older drivers like 430, 450, 460, 465 and 470 and no matter what I did I could not get the GPU to function correctly through XCP-NG.
I know there's no hardware problem as I have pretty much given up and it's currently doing hardware transcoding just fine on a Ubuntu 20.04 install on bare metal.
I'd be willing to give XCP-NG one last try if anyone can give me any suggestions as what could be wrong.
I'm not sure if it's the same thing, but I tried both passing through the PCI devices in the CLI as well as trying the method of selecting the Nvidia GPU from the list in XOA after I had disabled the GPU from the hypervisor. Neither method worked. I also tried assigning the GPU through XCP-NG center Windows program.
This screenshot shows a few different commands. You can see the error messages in dmesg as well as the GPU UUID and Video BIOS appear as blank when inspecting the device information under /proc.
