Public bug reported:
list operations in ovs_lib returns an empty list even if Runtime Error occurs.
As a result, when Runtime Error occurs, a caller thinks all ovs ports have
disappeared.
ovs-vsctl sometimes fails (mostly raises alarm error?)
ovs_lib should provide a way to distinguish these two situations.
list operations in ovs_lib
- get_vif_port_set (used by OVS agent and ryu agent)
- get_vif_ports (used by NEC agent, OVS cleanup)
- get_bridge (used by OVS agent, OVS cleanup)
It affects all agent using the above list operation.
It affects OVS agent and NEC agent. It triggers unexpected port
deletions.
In OVS cleanup, there is no negative effect. It just nothing for this
case.
