I've been having errors and breakage with gpu passthrough on all my hosts I've upgraded to 7.2 with kernel 5.15.30. Downgrading the pve servers to kernel 5.13.x fixes the issue for me. I'm doing some testing and will file a bug when I have some concrete data to give PVE devs.

I'll also note that mainline kernels 5.15.33 to 5.15.36 report a lot of vfio and iommu related fixes and changes - I'll test those too in case they fix the issue in 5.15.30

And I was wondering why my GPU passthrough broke after updating to 7.2..

Apparantly aafter pinning my kernel to
Bash:
proxmox-boot-tool kernel pin 5.13.19-6-pv
issue resolved it self.
Also I've stopped getting
Bash:

Nothing to do with the gpu and the node, it's the drivers detecting a vm, I got the wrong driver.
