hi, here's a blueprint to make OVS agent use Ryu to talk with OVS. https://blueprints.launchpad.net/neutron/+spec/ovs-ofctl-to-python https://review.openstack.org/#/c/138980/ (kilo spec) given that ML2/OVS is one of the most popular plugins and the proposal has a few possible controversial points, i want to ask wider opinions. - it introduces a new requirement for OVS agent. (Ryu) - it makes OVS agent require newer OVS version than it currently does. - what to do for xenapi support is still under investigation/research. - possible security impact. please comment on gerrit if you have any opinions. thank you.
