XPS 9350 Thunderbolt 3 eGPU PCI Passthrough

I'm trying to pass my GPU to a virtual guest on my XPS 9350. I've tested with the following hardware:
Razer Core
Akitio Thunder 2 + TB2 to TB3 adapter
GTX 560
GTX970

I followed the PCI passthrough via OVMF wiki article to the tee and am only passing the leaf peripherals (GPU, network adapter, etc.) and not the TB3 root hub. The guest enumerates both GPUs with generic drivers on both Windows 10 and Ubuntu 16.04, but after installing NVIDIA proprietary drivers I experience black and white screens, blank windows, windows not updating, and system hangs (host). I experience this with both GPUs and TB adapters.

$ for iommu_group in $(find /sys/kernel/iommu_groups/ -maxdepth 1 -mindepth 1 -type d); do echo "IOMMU group $(basename "$iommu_group")"; for device in $(\ls -1 "$iommu_group"/devices/); do echo -n $'\t'; lspci -nns "$device"; done; done

Has anyone attempted this, or have any advice?

Re: XPS 9350 Thunderbolt 3 eGPU PCI Passthrough

Did you find a solution for this problem?

I am thinking about doing the same thing (need to use some productivity tools in a VM).
Do you think an AMD GPU would work or is this problem related to the laptop?
