I was mostly hoping qemu would get paravirtualized support some day, because it is leagues ahead of VMware Player in speed. Everyone's hopes are riding on https://github.com/virtio-win/kvm-guest-drivers-windows/pull....
I just think it should be the objective of vendors to offer actual GPU virtualization first and to support paravirtualization as an optimization in the cases where it is useful or superior and the tradeoffs are acceptable.
