VirtualBox looks to be the first on the top of the virtualization pile with this one:

VirtualBox 3.0 Beta 1 has added Direct3D and OpenGL 2.0 support to their virtualization product, which means that those Windows Vista and Windows 7 virtual machines will finally be able to enjoy the Windows Aero UI that they so deserve.
For me, I think this could be a real driver for VDI (Virtual Desktop Infrastructure) as I think that main hold-back up until now has been the visual appearance of VDI (or rather the lack of).
I was rather hoping Microsoft could have managed Direct3D in Server 2008 R2 Hyper-V or Hyper-V Server R2 but obviously not as they use a graphics card much in common with VMware’s offering.
Hopefully this advance from VirtualBox will move them both along because we all know once one jumps the other will follow.
