Black screen at VM Console when installing Nvidia drivers to passthrough GPU
-
I’m getting a black screen at the VM Console when installing Nvidia drivers via my passthrough GPU (Nvidia L40). I’ve tried all different versions of Complete vGPU X package for XenServer 8 downloaded from https://ui.licensing.nvidia.com/software. Each one results in this black screen. I am at a loss now, I do not have any more ideas of what I can do to fix this. These packages all support my OS, my version of xcp-ng and my GPU. Has anyone experienced this before that might be able to help me figure this out?

Successfully passed through:
However as soon as it installed the Nvidia driver the Xen Orchestra goes to a black screen and never recovers. I’ve had to use RDP to uninstall the driver for troubleshooting.

If you are doing passthrough of the entire GPU, you don't need Nvidia vGPU drivers at all.

@olivierlambert I removed all traces of vgpu packages in xcp-ng and the drivers associated with them in my Windows server 2022 VM. I then installed the latest available driver release for the L40 GPU. The driver installed successfully and I can see it in Device Manager. But I do not see it in task manager. Is this normal for passthrough in Windows?

That's beyond my knowledge of Windows. Can you try to run a GPU related task and see the outcome?

@olivierlambert FurMark won't open because it cannot detect OpenGL 1.1 indicating a driver issue
