Nvdia Tesla P4 Passthrough to Windows Guest

[UgenPorter]

Hi,

I've have installed a Tesla P4 in my server and I want to pass it through to my Windows 11 guest, which I'd like to use with Autodesk Fusion with hardware acceleration. For the installation I have followed a solution from this thread - https://forum.proxmox.com/threads/proxmox-gpu-passthrough.157854/ .

I think it worked so far - I have the driver installed in the Windows guest and it is listed as graphics adapter, but there is still an PCI device list w/o any drivers and my Fusion installation is not detecting the GPU and in the task manager it is also not listed. Though in nvidia-smi on the guest it is available.

What's the problem, what could I check?

Do I need a license for this GPU, though it is directly passthrough to one guest?

Thanks guys

I have now tried to create new VMs and install Windows 11 from scratch using the following guides from reddit

I can see my installed Nvidia Tesla P4 in the device manager, but not in the task manager .... so it is not usable

use `nvidia-smi` check if your P4 in TCC or WDDM mode. Try `nvidia-smi -fdm 0` if not in WDDM mode. Then you should see the GPU from task manager.
