Best bet at this time is to extract the guest config

   virsh dumpxml [guest name]  >  guest.xml

Edit the guest.xml to change the name, UUID, MAC address & point to a
copy of the filesystems, then load the config back into XenD

   virsh define guest.xml

In the next update of  python-virtinst in Fedora we are also adding a
command explicitly for cloning existing guests called 'virt-clone'
which will make this task much much easier :-)

Dan.
