Affected TemplateVMs:

Own created custom win 7 x64

Steps to reproduce the behavior:

I have an optimus/hybrid notebook with an Intel and Nvidia GTX 950M cards. I have created  a win7 hvm and installed QWT successfully. I followed the guide below to passthrough 3D video controller pci ID and audio to win 7.

I followed this guide to passthrough the NVIDIA card https://paste.debian.net/1043341/ up to the part where you attach the pci IDs to the win hvm.

original post: https://www.reddit.com/r/Qubes/comments/9hp3e7/gpu_passthrough_howto/

In windows,

The win hvm was successfully started after I've changed the memory to 3.5G affter I had it set to 5G in qubes settings as was mentioned in the reddit post. In device manager, it can see the 3D controller but as an unknown so it needs a driver.  I downloaded the offiicial nvidia installer in attempt to install the driver but it said an error "windows incompatiable version". I am not sure if there's a way to do this. I just need the nvidia on windows to use some CAD applications. Any tips on how this can be done, if possible.

I think Nvidia have logic in the (consumer) driver to detect when it’s running under XEN (and other hypervisors) and will refuse to load/install in that environment.

With QEMU/KVM you can hide the VM from the driver.  I don't know how to do this with qubes maybe someone else can step in.  I didn't want Nvidia breaking my setup in a future driver update so I am using an AMD RX590 avoiding Nvidia's shortsightedness.  And they lost a sale.
