After your comment and (re)watching the added below YouTube vid, I got it working! Got it working using pcie_acs_override=downstream,multifunction and modprobe.blacklist=nouveau. Thanks a lot! Can boot VM with my 2080 AND transcode vids on my 750. Thanks again!

Indeed they're on the same bus. Both 2:00.0 and 01:00.0 are stubbed with the VFIO-pci driver. Indeed even though I only intended to stub 01:00.0.

Hi, thanks for creating this awesome plugin. This plugin is not working if I have 1 of the two GPUs installed in my system (one GTX 750 Ti and one RTX 2080) excluded for my VM with VFIO. Situation: GTX 750 ti (ideally to use for docker container, GPU transcoding etc.) RTX 2080 (passthrough to VM, excluded via VFIO flag) Error: NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running. and from `dmesg`: ``` [ 23.725090] nvidia-nvlink: Nvlink Core is being initialized, major device number 246 [ 23.726094] NVRM: The NVIDIA probe routine was not called for 2 device(s). [ 23.726897] NVRM: This can occur when a driver such as: NVRM: nouveau, rivafb, nvidiafb or rivatv NVRM: was loaded and obtained ownership of the NVIDIA device(s).
