Win 11 22H2, 7950x, nvidia 1070 Code 43 :(

Hello

I am pretty new to proxmox. I have recently upgraded my server to an AMD 7950x from a 5950x. I have been trying to get the GPU passthrough to work. I managed to get it working this morning on a new Windows 11 install everything seemed to work perfectly.

I then updated the VM to the 22H2 update for windows 11, and I am back to getting a code 43 issue on the GPU. Is there anything obvious I am missing?

Thanks

Pass-through also works if I use KVM64 CPU type instead of Host, but I think I need to use "Host" to get nested virtualisation, which I need for work.

if it worked with a previous version of the guest os and you did not change anything on the host side, i believe it's a guest os/driver problem sadly

you can ofc post your logs/config, and try to use another guest os (e.g. windows10/ubuntu/etc.) to verify if it works there

Hey, mine was working before I upgraded my proxmox. I remove my GPU, it boots. As soon as I do passthrough, it stops working. I upgraded to 7.3-6.
