XMLs or {libvirtd,qemu,...}.config files? For the former I suggest 'virsh dumpxml $dom > dom.xml' and copying over the file onto new machine and defining the domain again 'virsh define dom.xml' (s/dumpxml/net-dumpxml/ and s/define/net-define/ for networks and so on). If you run new enough libvirt there's even 'virsh migrate --offline' that encapsulates steps from above. For the latter just copy over the files onto new machine. In theory, copying over XMLs should work too, but we don't really like seeing users touching those behind libvirt's back as 'virsh define' does more than just saving the XML file. Michal
