Hi For live-migrations the supported procedure is the libvirt hook, note that live migrations requires a close synchronization between the image movements, memory movements and the hypervisors. OpenNebula cannot perform the login/logout from the iSCSI sessions there. Cold migrations are handled by opennebula as part of the save and restore commands.
