    Why not use normal GPU passthrough? I don't see how you can use this to share a GPU between multiple VMs, so what is the benefit of using this software over normal GPU passthrough with vfio-pci drivers?

      README mentions it supports up to 4 guests at a time sharing the GPU.

        I am wondering how they managed to achieve that without using Nvidia vGPU drivers.
