Since I read about this a few years ago I really want to try it, but I don't want to buy an extra GPU for it. I hope AMD [0] brings their SR-IOV implementation called MxGPU down to their mainstream GPUs, which allows to split a single GPU between host and guests. Apparently this would also be more secure than passthrough? In order to not affect their pro GPU sales they could maybe limit the number of virtual GPUs from 16 to 2, which would be enough for the host and a single guest. [0] or Nvidia, I don't care, but since Nvidia is the market leader they have less incentive than AMD.
