[SOLVED] Can't use PVE 6.x :'(

[Bestbeast]

Hello,

I am willing to use the new pve 6.x but it seems, that my pcie passthrough igpu to windows VM is not working correctly.
If you know what might be happening, to solve this, I will switch to proxmox VE 6.x, but until I have the stability to do it, I won't.
I have tried all guides I could found to make it work like:

https://lunar.computer/posts/gpu-passthrough-proxmox-60/
https://www.reddit.com/r/homelab/comments/b5xpua/the_ultimate_beginners_guide_to_gpu_passthrough/
https://ipcamtalk.com/threads/proxmox-virtualization-with-hw-acceleration.33175/
https://pve.proxmox.com/wiki/Pci_passthrough

It seems that my processor might not be compatible with some of the new stuff that proxmox 6 has on it. Any clue on what can be the problem?

Kind regards

What exactly are you trying to pass to the VM? Can you post your VM config and dmesg | grep -e DMAR -e IOMMU?

Hello,

iGPU is only working for me in proxmox 5.4 under Windows 10 without crashing as with 6.1. Any idea?

So, it seems really weird, I spent like 2 makes making it work, and only could achive it on PVE 5.4 and I have tried again, and seems to be working on PVE 6.1. So no clue what was going on, the other days.
Does it seems fine for you what is showing?

Kind regards

Looks ok. It would be great if you could mark the thread as solved by editing the top post. You are, of course, free to open a new thread if something goes wrong again!
