NixOS + Proxmox Hypervisor with SPICE and VirtIO-GPU

spiceproxy works!

I could not find any code to enable this, maybe it's out there but I did not see it. I created a pull request upstream here.

Overview

This is my config for running the Proxmox Hypervisor on NixOS with SPICE working. After trying it out and getting a Debian 12 VM running, I encountered an issue where SPICE was not functioning. It turned out that there was just a stub commented out in the proxmox-nixos repository. I added the necessary code in my flake.nix to make sure it is started with systemd.

Currently, SPICE with qxl or virtio/VirtIO-GPU works. virt-viewer automatically opens and resizes as expected when using the Console -> SPICE option with virtio. However, VirtIO-GL is not yet working on my system.

Features

• SPICE (qxl): Working
• VirGL GPU (virtio-gl): Not working yet
• VirtIO-GPU (virtio): Working (virt-viewer opens automatically and resizes)

Setup

1. Proxmox Hypervisor Setup on NixOS I followed the Proxmox Hypervisor setup on NixOS instructions to get started (using a flake).

2. SPICE Configuration The SPICE section in the proxmox-nixos code was initially commented out (see the code here). I modified my flake to make sure spiceproxy is included and started by systemd.

3. VirtIO-GPU Setup VirtIO-GPU (virt-viewer) opens automatically and resizes when using the Console -> SPICE option.

Known Issues

• VirtIO-GL: Not working yet. If you try to enable VirGL GPU, you will encounter an error message about missing libraries.

  TASK ERROR: missing libraries for 'virtio-gl' detected! Please install 'libgl1' and 'libegl1'

I've only been using NixOS for two days, but this is working so I thought I'd put it out there. I'm sure there are better ways to handle a couple of things, but SPICE with QXL and VirtIO-GPU are working.
