There'll be Pacifica support in Xen, it's just not fully baked yet.

Unmodified BSD / Linux / Windows should run fine under hardware-supported full 
virtualisation.

Heheh :-)

Yup.  We'll see what happens...  People running an OS under full 
virtualisation helps make the case for adopting paravirtualisation support.
