Jellyfin on Proxmox (feddit.de)

I want to use Jellyfin on Proxmox, if that is a thing. After reading a post here where most people recommended Debian as host OS I want to make a VM running Debian and install Jellyfin Server there.

Now I have a few questions:

  • I see many people install Jellyfin via docker. Does that have any advantages? I would prefer to avoid docker as it adds a level of complexity for me.

  • where do I save my media? I have a loose plan to run a second VM running openMediaVault where all my HDDs are passed through and then use NFS to mount a folder on the Jellyfin VM. Is that a sane path?

  • what do I have to consider on Proxmox, to get the best hardware results on Jellyfin? Do I need some special passthrough magic to get it running smoothly? I don't have a dedicated GPU, does that make the configuration easier?

My experience with LXC hasn't been ideal, but for reasons that are by design. The permissions make it complicated for the way I use it. Proxmox has all of the storage, which is shared with the LXC as a Mount Point. The LXC has unique user PIDs and GIDs, so if the LXC modifies a file, now none of my other stuff has permission to access it.

I had to add some config stuff to get around this problem, but in the end I just switched to VMs. I don't care about overhead that much.

Edit to add more info: I think the permissions problem is only if you make the container "unprivileged". The relevant config to add to /etc/pve/lxc/***.conf is as follows:

unprivileged: 1
lxc.idmap: u 0 100000 1000
lxc.idmap: g 0 100000 1000
lxc.idmap: u 1000 1000 1
lxc.idmap: g 1000 1000 1
lxc.idmap: u 1001 101001 64535
lxc.idmap: g 1001 101001 64535

I have no clue why this works. I think I copied it from Proxmox documentation. It worked and I left it at that.
