Hardware Transcoding with Intel UHD Graphics 605 on Proxmox Privileged LXC

[Fate]

My mounts look a bit different in lxc conf:

Code:

lxc.cgroup2.devices.allow: c 226:0 rwm
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.cgroup2.devices.allow: c 29:0 rwm
lxc.mount.entry: /dev/fb0 dev/fb0 none bind,optional,create=file
lxc.mount.entry: /dev/dri dev/dri none bind,optional,create=dir
lxc.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file

Was your container always privileged? I think if you have changed from unprivileged to privileged you have to reset the user/group ids. (probably easier to reinstall the container)

I would recommend tteck scripts to create your container if you are unsure.

Which intel drivers did you install on the proxmox and on the lxc side?
