Hello, I'm having a persistent issue passing my NVIDIA GTX 1080 Ti to a dockurr/windows container. The passthrough fails and Windows only sees a virtual display adapter. I have spent a long time troubleshooting this and have tried all the standard fixes. Symptoms: The container starts successfully. Running nvidia-smi inside the container works, but it shows "No running processes." The Windows guest OS only sees a "Microsoft Basic Display Adapter" in Device Manager. What I Have Already Tried and Confirmed: Hardware Virtualization: BIOS VT-x and VT-d are both enabled; KVM is active (/dev/kvm exists). Unraid Host: The Nvidia-Driver plugin is installed and nvidia-smi works correctly on the Unraid host. Docker Config: The container is configured with the --runtime=nvidia and --gpus all extra parameters. VBIOS: I successfully dumped a VBIOS file from the card using a temporary VM. The file is correctly mapped to the container's /vbios path, and the MANUAL_VBIOS environment variable is set to point to it. Headless Operation: The server is running "headless." The monitor is physically disconnected from the GPU, and the video=efifb:off kernel flag has been added to the boot configuration. Server Firewall: We have forcibly disabled the Unraid firewall by adding USE_NF="no" to the network.cfg file and rebooting. Despite all of these steps, the GPU is still not being recognized by the Windows guest. I have attached my server's diagnostic file. Any insight would be greatly appreciated. thinkstation-diagnostics-20250827-1002.zip
