Hello,
 
Is it possible to:
 
Setup a dual boot using WinXp and Fedora 6 ---- then boot into Fedora using the xen kernel,
start the virtual manager and boot the windows operating system that is already installed???
This would most likely require setting up a separate hardware profile within windows.
 
I came across such an article (PDF) sometime ago, but now I can not find/Google it. 
 
Thanks Cmotley
