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?

    If it wasn’t connected via PCIe how would it talk to the GPU. Anyway Proxmox does in fact not officially support ARM so that is a pretty miniscule use case. I’m not even sure why you would want Proxmox on a low powered device.

    For me PCIe pass though is the easiest. Virtualization adds little overhead in terms of raw performance so it isn’t a big deal. If you prefer LXC that’s fine but my initial statement was based on my own experiences.

      AMBA/AXI-bus in the case of the Pi. GPUs existed long before PCIe did lol.

      One some x86 systems the CPU and GPU aren’t connected with PCIe either. AMD has infinity fabric that they use for things like the Instinct MI300 and some of their other APUs

      Edit: Oh yeah also ARM isn’t just low power anymore. It’s used in data centers and super computers these days. Even if it was there is lots of stuff you can do with a low power node, including running file servers, DNS or Pi hole, web servers, torrent/usenet downloaders, image and music servers, etc. I have also seen them used to maintain cluster quorum after loss of one more powerful node. A two node cluster won’t have quorum if one fails, so adding a pi as a third node makes sense.
