Running Parallels or Fusion with bootcamp?

Hello, on my mbp i have win xp installed using bootcamp, an i want to know what will happin if i put parallels or fusion on the mac, will it create another partition an install another win xp then ill have to install my xp programs again to use them via parallels or fusion? or with it jus tap into my bootcamp xp? thanks

They can do either or both.

If you want to be able to access and run the same install of windows in a VM as you run in bootcamp both Fusion and Parallels can do that.

ok, thanks =]
