This is still not quite working correctly. The following command
must *not* run

  # virsh -c qemu+ssh://root@avocado/system migrate vm1 --offline qemu+ssh://root@mustard/system 

because it does not include the '--persistent' flag.

If I do set the --persistent flag though, that is now
correctly operating. Likewise --undefinesource is
working now.

The other bug remaining is that you are still creating
an XML file /var/run/libvirt/qemu/$GUESTNAME.xml for
the inactive guest. This is bogus, because that file
should only exist if the guest is running.
