Newbie Help with Intel N150 iGPU Passthrough Please

[Astaroth]

Hi,

I'm new to Proxmox and Linux and trying to set up Jellyfin in an LXC on a GMKTec G3 Plus with Intel N150 CPU. I was following a guide which said to install the "intel-media-va-driver-non-free" driver, but this didn't work. I then found another thread here which said to use "intel-media-va-driver" instead for this CPU, so I removed the 'non-free' version and installed that instead. The driver is now working (according to vainfo) in the host, but not in the LXC. Is anyone able to help please as I'm now struggling. I've included as much info as I can below.

I'm using a fresh install of Proxmox 9.0.5 and ran the 'Proxmox VE Post Install' helper script to configure the sources etc.

LXC .conf file
I added the following to the config file (with container off). The guide I was following had "226:0" on the first line, but AI told me the 0 is the ID of the card which shows as "card1" on my host, so I changed that to a 1.

The last line had "0:108" in the guide, but the video group ID on my host is 44 (see lxc output below), so I changed that too (again listening to AI).

lxc.cgroup2.devices.allow: c 226:1 rwm
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file
lxc.hook.pre-start: sh -c "chown 0:44 /dev/dri/renderD128"

LXC output (as root) - Ubuntu 22.04
I haven't installed jellyfin yet. Container is privileged... I understand that's a security risk due to it having access to the host OS/kernel but Jellyfin's documentation says it's required. I also need to give it access to NFS or SMB to read media from my NAS which I believe requires this too. I don't intend to make this accessible over the Internet, so hoping it will be ok.
