[libvirt-users] Reg: Packaging format for LIBIVRT

Hi, I am looking for an available Open Source Packaging model for Libvirt, similar to OVF/OVA supported by Vmware. The OVA model uses the manifest to define the resource requirements for the virtual appliance and the XML schema follows OVF. Are there similar specification to include libvirt XML in a package along with disk images/ISO... etc? Any pointers in this regard would be useful. Thanks, Alphonse
