    With Virtualbox also having a recent new release, it might be time for some new virtualization benchmarks

      I was contemplating what VirtIO GPU support meant but then I read that 3D is still "being worked on". What a great day it will be when 3D works properly so we can run Nvidia Windows drivers and Linux at the same time and Game on both.

        This won't happen. VirtIO GPU is about exposing virtual graphics card that would require custom guest system driver to provide you with GPU acceleration. So basically it's will require own Windows driver just like Spice/QXL now, but likely will bring much better 2D / 3D performance for guests.

        It's based on Gallium3D so it's should also bring good level of 3D performance for Direct3D 9, but of course there is nothing for Direct3D 10 and above except VMWare eventually release their proprietary state tracker.

          Perhaps you are thinking about "VGA Passthrough".

            Perhaps, care to elaborate? Thanks

              Thing is though, you need a second card to pass through to the guest OS. And it is very iffy at the moment.

                You basically assign a secondary graphics card to the guest OS. That card becomes "invisible" to the host OS, but "real" to the guest OS: there is no emulation, just plain direct access; guest OS even loads native drivers for the card. When it works (and that is a big "when"), it works at nearly native performance.

                  Vids on youtube demonstrating it.
