NVIDIA GPU Passthrough: Code 43

[stewart]

Hello.

I'm new to Proxmox and I've got a brand new environment setup on the below hardware. I want to passthrough my GPU to a Windows 11 VM and I've followed the below guides and have gotten right to the end where I'm now faced with a code 43 on my GPU.

The only thing I had to diverge from the guides on is the BIOS settings. My board doesn't have IOMMU settings, but did let me enable VT-d. This made me wonder whether I need to change the line from the below to something referencing VT-d but I'm none the wiser.
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"

Guides followed:

Hardware:

Intel i7-10700KF @ 3.80GHz, 16 cores
32GB DDR4 Memory
500GB Kingston SSD
4 x 4TB WD Red HDD (unused so far)
NVIDIA GeForce GTX 1050 Ti (GigaByte)
MSI Z590 PRO WiFi

Your input would be greatly appreciated.

Did you install the geforce drivers inside the VM?

Passthrough is some kind or working, becauses otherwise you wouldn't see the GPU inside the VM and the VM wouldn't start at all.

You could try the 472 drivers. The new one causes alot of troubles.

I've just tried 472.12 and am still getting the same result. Thanks for the suggestion.
