PSA for anyone using #QEMU #KVM for #SingleGPUPassthrough
Guides are all over the net suggesting hooks scripts invoking pci devices, unloading/loading kernel modules, and other unnecessary things. Here's my current hook script for starting the VM:

That's it. And the reverse for teardown:

#IOMMU groups still apply, and you need to pass the correct PCI devices to your VM, but everything else is handled automatically.

Disclaimer that this is how it works currently for my AMD card. I did have a working setup with my NVIDIA card that did unload/load kernel modules, however it seems things have come a long way since I set that up.

lmao, Chris Titus Tech had an update to Looking Glass and now he can't access his Windows VM.

This is why vGPUs are important!

If anyone wants to passthrough their integrated GPU on an AMD Ryzen 7000 series, peep this. But I will say, it's actually not worth it. The reset bug is here despite the fact AMD has fixed it in Big Navi, and vendor-reset ain't gonna help. Just use an NVIDIA GPU instead, it'll be easier. Or just use VirtualBox if it's simple enough.

🎮 GPU Passthrough + Looking Glass sur Ubuntu

A découvrir un setup hybride : une VM Windows avec GPU dédié accessible directement sur la TV ou bien soit via Looking Glass depuis le PC natif sous ubuntu sans latence.

Performances natives (ou presque) pour la VM Windows, le hote Linux toujours dispo et utilisable permettant d'avoir une flexibilité totale.

"Failure is simply the opportunity to begin again, this time more intelligently." — Henry Ford.

Introducing VxM, a hypervisor orchestration utility for Nitrux.

Concurrent, hardware-accelerated guest execution on multi-GPU workstations.

Coming to Nitrux 6.0.0

Hi, I'm Sparrow. I run KstrlWorks where we build high-performance, privacy-first tools for Linux users.

Built systems for F-35s and high-frequency trading desks. Now an executive that companies with deep pockets parachute into their disasters to fix operations and actually grow them.

Currently shipping:
HardPass - GPU passthrough and #VFIO that actually works. For #LinuxGaming and power users.

I write about:
- Real #EngineeringLeadership. The kind that prevents incidents, not LinkedIn motivational posters.
- Running efficient, security-first teams that don't implode
- #Virtualization, systems architecture, and #Bootstrapping
- Building infrastructure so solid you never need to hire a fixer like me

High-performance, privacy-first tools built with the same standards I use for critical systems. Linux users deserve that.

Let's build things that work. 🐧

RTX 5090 + llama.cpp bị treo sau 2-3 lần chạy mô hình (cấu hình VFIO, Ubuntu 24.04). Lỗi "illegal memory access", GPU lỗi, quạt quay 100%. Đã thử nhiều cách nhưng chưa khắc phục. Hỏi: lỗi từ Blackwell, driver, hay nên dùng Windows VM? #llamaCPP #RTX5090 #GPU #MLOps #VFIO #CUDA #Linux #LỗiGPU #AIModel #Ubuntu

WHY IS IT SO HARD TO DUMP A VBIOS

#server #gpu #vfio #proxmox

So my HP Prolaint ML350 Gen 9 has a intigrated matrox gpu in the motherboard but apparently still would rather piggyback of whatever gpu is installed by shadowing its vbios so now i have isssues with my intel arc a310. Good job HP
