Hello,

I am trying to pass through my GTX 1030 to a Windows 11 virtual machine on Proxmox, but I am running into an issue. When I start the VM, the GPU is not recognized and I get an error 43 in the Device Manager.

I have followed the Proxmox documentation on GPU passthrough --> https://pve.proxmox.com/wiki/Pci_passthrough

some information about my configuration proxmox :

Hello i found this :
Code: 
root@proxmox2:~# dmesg | grep 'remapping'
[    0.146194] DMAR-IR: Queued invalidation will be enabled to support x2apic and Intr-remapping.
[    0.147721] DMAR-IR: Enabled IRQ remapping in x2apic mode

maybe somethings going wrong on this line ?

[ 0.146194] DMAR-IR: Queued invalidation will be enabled to support x2apic and Intr-remapping.


what do u think please ?
 
Hey, have you tried to add a patched ROM or at least the original one?

Here is a how-to that helped me a lot and there is a section about the rom file at the end: https://www.reddit.com/r/homelab/comments/b5xpua/the_ultimate_beginners_guide_to_gpu_passthrough/

In addition, maybe watch into this git repository, it‘s a patcher for gtx 10xx card‘s roms and there is a troubleshooting section about error 43. But first try to patch and add a rom file:

(How) did you patch the rom?

whi don"'t do it

i don"t understand how to do that

i try to make it on my Virtual W11
i try this in my vm :

5. Open powershell and run patcher.ps1 C:/NVIDIA/DisplayDriver/Version/Win10_64/International/Display.Driver
6. Install Driver Through Extracted Installer (In C:/NVIDIA/DisplayDriver/Version)

and restart and nothing works :/
 
Nope that's not what I mean. You can either use this tool or send me your rom and I patch it for you. Nvidia breaks passthrough on purpose because, well, it's nvidia :/.
EDIT: what do you mean with "nothing works"? Still "just" error 43 or isn't it working at all anymore?

Okay, you already patched it, right? Have you tried booting with GFX set to default (so you can use noVNC) and the GPU passed through but not as primary GPU? Then you can install the drivers and shut down the vm. Now set GFX to none and the GPU as primary. Maybe that helps. What is the manufactorer of the GPU? Have you tried updating the vBIOS of the card?
 
First, set graphic card to default and uncheck primary gpu for your gtx 1030 in the hardware tab. Then boot windows and install the official nvidia drivers. Now, shut down the vm and set graphic card to none and check primary gpu in the hardware tab for your GPU.
If that doesn't work, try to dump your gpu vbios yourself. Do you have a working windows installation outside of proxmox that you can boot native?

Another tip:
Set graphic card to default and uncheck primary gpu for your gtx 1030 in the hardware tab. Boot Windows and access with noVNC.
Disable and enable graphic card in device manager.
