technolink,
I did not have any issue when running Window 8 x64 VM on Fusion 6.0 TP1 build with hardware version 10.
One known issue, while upgrade/uninstall tools on Window 8 + Fusion 6.0 TP1, sometimes, it need wait for a few mintues with black screen. could you let us know what specfic issue did you have. it would be very nice with Fusion support log bundle uploaded.
Best Regards,
changhai
