Hello Folks,
I’m trying to pass through a GPU into my LXD VM, and having some great difficulties - here’s the steps I tried:
- blacklist
- nvidia
- snd_hda_intel
- Pass GPU via CDI notiation
- Fails with a warning about not being able to find the GPU
- Pass GPU directly via PCI address
- Pass GPU vendor & model ID
These last two attempts “worked” in that the GPU will configure via LXD, but when starting the VM it will just hang as “Running”. I tried to get more information via lxd info --show-log gpu-test - this produces a more-or-less blank output. Additionally I cannot SSH to, or access the VM via the LXD Agent.
Any ideas how I can troubleshoot this? Here’s my VM config:
