  > just using PCI passthrough

On a laptop, I never got a working setup where I could attach/detach a modern nvidia card from host linux. So something that can do without is better. But intel SRIOV is a thing as well, which should be the secure alternative.

I got it working on my laptop. It has an Intel integrated iGPU and an NVIDIA discrete dGPU. I was able to pass through the NVIDIA GPU and use it for CUDA/etc.

But the NVIDIA dGPU is muxless, so apparently all of the display outputs (laptop screen, HDMI outputs) are effectively hard wired to the iGPU. dGPU can render in a VM, it just has no where it can send it without trying to use Looking Glass or similar approach.
