I upgraded to Fusion 8.0 today and ran into a nasty bug where it crashes hard (freezes the whole Mac sometimes) if you boot into a virtual machine with hardware version 12 on a Mac using the Nvidia web driver. Solution is to either disable 3D acceleration in hardware version 12 or roll back to virtual hardware version 11. Sucks because I was looking forward to D3D10 and OpenGL 3.3 support in the new Fusion. Oh well... Filed a bug report / support request with VMWare.
