QEMU with VirtIO GPU Vulkan Support

With its latest reales qemu added the Venus patches so that virtio-gpu now support venus encapsulation for vulkan. This is one more piece to the puzzle towards full Vulkan support.

An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for VirtIO-GPU with a local development environment. Following up on the outdated write up, this is how its done today.

Let's start with the brief description of the projects mentioned in the post & extend them:

Mount Volumes into Proxmox VMs with Virtio-fs

Part of collection: Hyper-converged Homelab with Proxmox

15-04-2025: Seems Proxmox added this now to the GUI; see Using VirtioFS backed by CephFS for bind mounts how to use it.

Virtio-fs is a shared file system that lets virtual machines access a directory tree on the host. Unlike existing approaches, it is designed to offer local file system semantics and performance. The new virtiofsd-rs Rust daemon Proxmox 8 uses, is receiving the most attention for new feature development.

Performance is very good (while testing, almost the same as on the Proxmox host)

Running Windows 10/11 Guest with GPU Passthrough using laptop running Fedora

Abstract

This is a full guide for people who wanted to set up Windows 10/11 VM with QEMU/KVM hypervisor enhancements for a laptop that is configured with hybrid graphics card like Intel/AMD + NVIDIA. This process will take about 1 to 2 hours, depending on your system's performance and your patience =)

There is another comprehensive guide you can follow here (shoutout to asus-linux team who made supergfxctl which is a very important tool for this guide). It is more up-to-date than mine. I would probably incorporate those information into my guide, but you are welcome to use this one as a reference!

Before we proceed:

This guide is exclusively for Fedora users because this distro is quite different to set up than other distro such as Arch. I would say Arch is easier to setup than Fedora, but sometimes you like to use Fedora than Arc

Installing NFS inside LXC Container on Proxmox 5.1

Host Setup:

Create LXC Container as usual, but do not start it yet.

# Install NFS-Kernel on Host
apt install nfs-kernel-server

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

In a perfect world, where things are done well, not just quickly, I would expect to find the following when joining the company:

	# enable ipv6 in dockerd conf:

	# cat /etc/docker/daemon.json
	{
	"ipv6": true,
	"fixed-cidr-v6": "2003::/64" # your ipv6. not sure if this is even necessary
	}

	# reload daemon conf:
	sudo systemctl reload docker.service
