Public bug reported: When multiple api and rpc workers enabled for neutron-server, sometimes ovs agents fail to create flood flows to other ovs agents. This is frequently reproducible when multiple api and rpc workers enabled during migrations and also during evacuations of instances from one node to other. Some times tunnel ports are also not created.
In these scenarios, l2pop driver is not notifying agent to create tunnel ports and flood flows, hence agent is unable to create flood flows to other agents. ** Affects: neutron Importance: Undecided Assignee: venkata anil (anil-venkata) Status: In Progress ** Changed in: neutron Assignee: (unassigned) => venkata anil (anil-venkata) -- You received this bug notification because you are a member of Yahoo!
