As the other reply mentioned, you can use the webui for a quick GUI in a pinch, and as for QSV, I’ve had more luck passing through GPUs to LXC containers, as that’s what I’m doing for my Jellyfin setup with an Intel GPU in Proxmox. Link below can hopefully get you started
Yes, you can pass through any GPU to containers pretty easily, and if you are starting with a new VM you can also pass through easily there, but if you are trying to use an existing VM you can run into problems.
