The mkmountpoint call allows you to have multiple "roots":

http://libguestfs.org/guestfs.3.html#guestfs_mkmountpoint

*However*, this won't work for general guests, where for example two
guests might have conflicting logical volumes or UUIDs which are
duplicated.  It's simply not possible to safely mount multiple guests
in a single appliance.  The solution is to use two libguestfs handles.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into Xen guests.
