 +Due to NVIDIA GPUs needing a license to be able to use vGPU it's currently not really recommended to passthrough a vGPU but instead the whole GPU. The best approach for a desktop machine is to use the single GPU passthrough approach which stops the X server and starts up a pre-configured virtual machine.
