    There are lots of very exciting things coming to KVM and Xen, such as support for shared Intel integrated GPU passthrough with guest frame buffer redirection back to a host app window. I got to try it out the other day:

      I has been waited more than a year for that, maybe two years. Finally...

      How the performance compared to native? Do you haz benchmarks?
