Alright, I wanted to know if I could purchase Fusion from my school and use it to virtualize my installation of Windows XP? I used bootcamp to partition and install Windows. Can I just install Fusion and use it to virtualize my already installed XP or do I have to reinstall?? Also, asked in another thread as well, but wanted to know if I tell Fusion to use 1GB RAM for XP, when I am not running Fusion does Mac OS X go back to using all my RAM or is that RAM I specified for Windows to use gone for good from OS X? EDIT: Second question was answered in another thread a few minutes ago... RAM can be used by OS X when Fusion or Parallels is not running! Good to know!
