Tried installing Vista Ultimate x64 as a guest using vmware on ubuntu. Hangs after the first reboot. So I installed vmware on Windows and tried to install Vista x64 and Windows 7 but both of them also hang on a Windows host. Searched the internet, and this appears to be a common issue, though I didn't see any fixes for it out there. Any suggestions? I'm thinking of trying Virtual Box or Microsofts product if I can't get this fixed.
