Virtualization solution with decent graphical capabilities?

http://askubuntu.com – I've been using VirtualBox for a really, really long time and enjoyed it but now I need to run Unity3D and this seemingly simple task turned out to be too much for humble graphical abilities of VirtualBox. The thing is virtual box allows only up to 128mb of video memory (I've tried various tricks described over Internet to make it work with 256mb but with no luck) which is not enough for even IDE of Unity3D to start (it kind of starts but only kind of). Also with direct3d support enabled virtual box crashes when I try to do something in Unity and without it Unity3D IDE looks completely unus (HowTos)
