Well, the API documentation says VIR_MIGRATE_TUNNELLED and VIR_MIGRATE_PEER2PEER are not supported by this API, use virDomainMigrateToURI3 instead. so any direct user of this API should already call the right API. And virsh users would just see the new error and once they add the peer2peer flag, virsh will automatically use the correct API. So I guess it's good enough :-) Jirka -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
