One thing you can do is go ahead and install for multi-boot, but
also install the paravirt kernel (just don't make it the default),
then if you run your main system as Dom0, you can run the other
linux partitions as paravirt systems (just need the right xen
config files and pygrub options to make the virtual system boot the
xen kernel entry in grub).

I don't do this, mind you, but I did some experiments once, and
did get it to work. (P.S. Make sure you don't try to mount any
partitions in more than one system at a time :-).
