Yeah, I'd love to see something like that. I would really like to see more effort in this area. I honestly haven't been thinking about it much in a while personally, because the rest of the "make it work" gaps have still been a work in progress. There's a bit of a bigger set of questions here, too ... Should nova-network *ever* go away? Or will there always just be a choice between the basic/legacy nova-network option, and the new fancy SDN-enabling Neutron option? Is the Neutron team's time better spent on OpenDaylight integration than the existing open source plugins? Depending on the answers to those questions, the non-visible no-downtime migration path may be a less important issue. -- Russell Bryant _______________________________________________ OpenStack-dev mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
