This is the part that interests me the most :) Do you think in dealing with image backing file chains, libvirt would ever make use of QEMU auto-generated node-names (either in the current feature set, or with future features)? I'm not sure if your above statement is specific to device ID, or extends to node-names as well. Thanks, Jeff
