Sticking with qemu for the moment (but the same program can be used for
many formats); you can use qemu-img convert to copy your XP vdi to e.g.
qcow2 or RAW and use that for $other vm.

The openstack project has nice documentation on this:

Note though, that plain qemu can be a bit cumbersome, nice frontends are
available (I've used libvirt with some success in the past).
