Hello, I hope I can get some help here.
I am using jellyfin as media server. And it stopped working somewhere between now and like a year ago or so. I don't use it very often. So some update must have changed something which I didn't observe - so no clue what actually was the change that broke it - bummer!
The thing is: When I now install a fresh new debian VM (or Arch or whatever) and then install the NVIDIA driver like mentioned here:
https://wiki.debian.org/NvidiaGraphicsDrivers#Debian_12_.22Bookworm.22 (just an example, for arch this would differ ofc, for most of my VMs I use Debian though, so the example fits best))
Everything looks good, I reboot and test it via nvidia-smi and the dreaded "No devices were found error" hits me. Which is funny, because the system can see my Nvidia GPU... Without a proper passthrough and a proper driver installed and used I cannot use my GPU fpr Jellyfin transcoding, obv...
The basics:
The proxmox server is an AMD EPYC 7551P on a Supermicro H11SSL-i rev. 2.0, the respective GPU is a Quadro P620 from Nvidia. I think the rest of the hardware does not matter here. proxmox is on it's newest release, just made an upgrade.
My grub for IOMMU looks like this:
My VM setup looks like this:
And within the VM I blacklist nouveau:
The driver is loaded properly:
But still this:
I hope somebody can help me, because I do not often use my Jellyfin, but when it is together with my wife. Which is quite unhappy and already told me "With an apple everything would be working"...
