I have a used Lenovo Thinkcenter 910 with a i5 7500T running Proxmox with Linux Mint in one VM and Adguard running in another. I’m just getting started so I am reading/searching for tons of answers still
I was hoping to host Jellyfin within Linux Mint. It works pretty well, but I did notice while watching a movie the CPU was pretty well pegged out. I wanted to enable hardware based acceleration but when I started reading setup guides to hope to understand what I was doing, I think I may have painted myself into a corner already.
I think I need to tell Proxmox to pass the hardware acceleration on to Linux, and then get Linux to, but also some of the things I have read make it sound like I need to have set up the VM from the beginning this way.
Am I trying to do this the hard way somehow? Does anyone have any suggestions on the best guide to follow for this?
Don’t do that. Run Jellyfin in its own VM with a GPU passed though via pcie passthough.
That’s going to be almost impossible to do with an iGPU. Makes way more sense to pass through to LXC.
It takes about 2-3 clicks. What do you mean impossible? LXC is likely faster but it takes more setup.
2-3 clicks? That’s hilarious!
These are the steps it actually takes: https://3os.org/infrastructure/proxmox/gpu-passthrough/igpu-passthrough-to-vm/
That’s the best case scenario where it actually works without significant issues, which I am told is rarely the case with iGPUs.
In my case it was considerably more complicated as I have two GPUs from Nvidia (one used for host display outout), so I needed to block specific IDs rather than whole kernel modules.
Plus you lose display access to the Proxmox server which is important if anything goes wrong. You can also only passthrough to one VM at a time. Compared to using LXC you can passthrough to almost unlimited containers, and still have display output for the host system. It almost never makes sense to use PCIe passthrough on an iGPU.
The reason to do passthrough is for gaming on Windows VMs. Another reason is because Nvidia support on Proxmox is poor.
This is a guide to do passthrough with LXC: https://blog.kye.dev/proxmox-gpu-passthrough
It’s actually a bit less complicated for privileged LXC, as they are having to work around the restrictions of unprivileged LXC containers.
I did this recently and I wish I could answer you, but I’m on mobile and don’t remember exactly what got it working. I also referenced the guide linked below, along with the proxmox documentation.
If you start blacklisting drivers, you’ve gone too far for passing through Intel quicksync. I think I’m the end it was a pretty basic config, like checking motherboard settings and adding text to the grub config.
Also don’t guides say you have to use q35 as the machine type for the VM, but that didn’t work for me. Only 440fx works for me.
Proxmox has an official guide on how to do this, which inlcudes these examples.
There’s also a video from Jim’s Garage where he sets up GPU passthrough in an unprivileged LXC container within proxmox.
See if any of that helps.
