Hi all, We have suffered a long down time when we upgrade our public cloud's neutron into the latest version (close to Juno RC2), for ovs-agent cleaned all flows in br-tun when it start.
I find our current design is remove all flows then add flow by entry, this will cause every network node will break off all tunnels between other network node and all compute node. ( plugins.openvswitch.agent.ovs_neutron_agent.OVSNeutronAgent.__init__ -> plugins.openvswitch.agent.ovs_neutron_agent.OVSNeutronAgent#setup_tunnel_br : self.tun_br.remove_all_flows() ) Do we have any mechanism or ideas to avoid this, or should we rethink current design? Welcome comments Wei Wang
