Hi everyone
I've undertaken a project of making a Proxmox server for machine learning and remote gaming, but I'm sort of stuck getting the Nvidia drivers to work on my Ubuntu 22.04 VM. The plan is to have a few VM's configured for either machine learning or playing games using different GPUs.
I am both new to this forum and a bit new to Linux, so please bear with me for any mistakes, and point out if I'm missing some info
So far I have successfully passed trough my 1060 to a Windows VM following the guide, but I can't seem to get the K80 working properly. The VM has been set up with both the two available GPU's from the K80, but i had a similar error before with a single K80 GPU VM.
My system has a MSI Z590 MB, Intel 10850k, a gtx 1060, and a Tesla K80.
I have mainly used this guide as a reference:
https://3os.org/infrastructure/prox...virtual-machine-gpu-passthrough-configuration
The only thing I have done inside the VM so far is to use the inbuilt "Software & Updates" to install the Nvidia 470 display driver.
The main symptom arises by running the
command:
Although the GPU's are listed when running
...
The best clue I have is this part from the
command:
(same error on the other GPU; PCI bus 0000:02)
The best suggestions I could find scouring the internet was to enable "above 4G decoding", and disable "CSM", both of which I have done in the host BIOS.
Any help or clues would be appreciated, as can't really find much info about this issue.
Update:
I've read through the forums a bit, and I found this very informative post by Lefuneste:

Where it was helpfully pointed out that by running
in the host, there should be a line with "vfio-pci" the line under the GPU PCIE adress, which I don't get. Instead, I get nothing the line under my GPU adresses. In fact, when running
, I get nothing. Does this mean that the Nvidia drivers are succesfully blocked from grabbing my GPU's, but the vfio fails to get it?
