Hi Francesco, I left it running after I posted to the list, and it eventually (after many failed attempts) moved the VM without any intervention by me, and then updated the host, so that explains the differences in the versions of qemu between the hosts (they probably would have been the same when I tried the move first). The xml is attached.
