Quadro K600 - Error 43

[jdnation]

Hi everyone, Right now I'm struggling trying to assign an Nvidia Quadro K600 to a Windows 10 virtual machine>

I manage to make all configuration in proxmox in order to passthrough the graphic card and the virtual machine recognize the card but there no way to get rid of error 43.

I'm using Proxmox PVE 8.4.14 on a HP Workstation Z400 with Intel Xeon X5675 Processor and with only one gpu card (Quadro K600). I really don't know if is even possible considering my hardware I've read that you need two graphics cards but also I've that is possible with only one card.

this is my .conf file

I really don't know if is even possible considering my hardware I've read that you need two graphics cards but also I've that is possible with only one card.

It is possible, but two GPUs are better because at the moment your VM starts, GPU disappears on host and you lose output for proxmox console. For debugging that is not the best situation to start with.

Anyway...you have error43 with Nvidia-drivers that got sucked in by win-updates automatically or did you download and install the whole package from nvidia.com ?

hostpci0: 0000:28:00.0,pcie=1,romfile=155387.rom <- the romfile is only necessary in exceptional cases

Well, I usually manage the proxmox server from the webui, so losing the video output is not a problem for now.

I download the whole package from nvidia.com

Regarding the file. I've tried with and without and the problem persist.

Add it this way, works 100% and worked in the past for Windows in VM (at the moment this VM doesn't run Windows).


Edit, there is some more help, but shouldn't be necessary:

Hello,

I am new on the proxmox.
I am trying to make gpu passthrough on a windows 10 vm.

I followed many guides like :
--> https://www.reddit.com/r/homelab/comments/b5xpua/the_ultimate_beginners_guide_to_gpu_passthrough/
--> https://pve.proxmox.com/wiki/Pci_passthrough

I am thinking that I am in a good way because in device manager of windows10 vm I can see the graphic card.
Also, I can see the windows home screen in my monitor.

The problem is that i got error43 in device manager.

I install the nvidia drivers with geforce experience.
**If i disable the device and enable...
