Hi The libvirt on Xen-3.03 does not have the function that add/change/delete a Disk/NIC of inactive domain. So, I made a patch which enabled add/change/delete of Disk/NIC of inactive domain. This patch will be able to change "disk" or "vif" parameter in configuration file with "attach-disk","attach-interface", "attach-device", "detach-disk", "detach-interface" and "detach-device" command, like "setmem" or "setvcpus".
