On the other hand, Mark Williamson, one of the Xen dev pointed on Xen devel ML on a very interesting document from Microsoft (http://download.microsoft.com/download/9/8/f/98f3fe47-dfc3-4e74-92a3-08878= 2200fe7/TWAR05013_WinHEC05.ppt) It seems that MS will follow an approach similar to Xen for their future virtualization technology (maybe because MS research was involved in Xen's first steps) We can dream and hope that it will be possible to adapt Xen to run MS VM (though I believe MS will do whatever is possible to make this impossible).
