How to setup VA-API within Proxmox LXC Unprivileged container

Proxmox configuration

No drivers need to be installed on the proxmox, from now called host.

Find GIDs of video and render group on host:

cat /etc/group | grep video

cat /etc/group | grep render

1. Add a virtual serial port to the VM using PVE Web GUI and restart the VM

2. Enable and start the virtual serial port on VM, change tty number as needed (Reference: https://askubuntu.com/a/621209/838946)
$ sudo systemctl enable serial-getty@ttyS0.service
$ sudo systemctl start serial-getty@ttyS0.service

3. Done! You can now select xterm.js in the PVE Web GUI

I ran into the battle of running all of my VMs and the host node under a single public IP address. Luckily, the host is just pure Debian, and ships with iptables.

What needs to be done is essentially to run all the VMs on a private internal network. Outbound internet access is done via NAT. Inbound access is via port forwarding.

Network configuration

Here’s how it’s done:

Create a virtual interface that serves as the gateway for your VMs:
