I think you’re referring to the ability to split a physical NVIDIA GPU into multiple virtual GPUs so that you can do full GPU pass-through with one card (without having to resort to hacks like disconnecting host sessions.)

What vm-curator provides is an easy way to use QEMU”s built in para-virtualization (virtio-vga-gl, a.k.a. virgl) in a manner that works with NVIDIA cards. This is not possible using libvirt based tools because of a bug between libvirt and NVIDIA’s Linux drivers.
