You may want to look at virt-sysprep, part of the libguestfs suite of
tools, which can automate a number of these tasks when creating
derivative cloned VMs.  From the tools perspective, most of your work
will be done outside of virsh, in prepping the new disk images and
creating new derivative xml, then finally calling into virsh to start
the new xml.
