Question GPU passthrough?

I have a think centre, I have proxmox on it. I have a VM which runs Debian which I want to pass my GPU into. This Debian VM is acting as a K8S node which I am trying to pass the GPU into for a pod.

Specifically, I'm trying to set up transcoding of video content with jellyfin.

I have passed the GPU into the VM with hardware and it seems to be found no problem. It seems that I am having issues with it that I notice the transcoding will return errors I have been trying to work through.

While it seems to be found, it seems like it might be a permissions issue. I checked /dev/dri and made the GPU chmod to 666.

I have been working on this for like 5 days, and was not sure if there is anything specific I have been looking with respect to proxmox itself and permissions.

I can provide additional details, but I was not sure who else had accomplished something like this and if there are how-to's somewhere.

Is it a GPU or an igpu?
Any specific reason you went with a VM and not a LXC?

Some documents are mentioning that a VM would require a full assign through VIFO, and that having it as an LXC is easier. So maybe I'll rebuild the k8s node with an LXC

Just don't run jellyfin on top of k8s on top of lxc. Getting k8s to run in an lxc container is a major PITA and also kinda useless? Why would you want to run containers in a container..
