Fixes bug 1085861 Live-migration with Ryu plugin doesn't work because the unique constraint of PortBinding table is violated as follows. Now Ryu can handle those informations itself, so remove the table itself and simplify Ryu plugin. > ERROR [quantum.api.v2.resource] update failed > Traceback (most recent call last): > File "/quantum/api/v2/resource.py", line 95, in resource > result = method(request=request, **args) > File "/quantum/api/v2/base.py", line 397, in update > obj = obj_updater(request.context, id, **kwargs) > File "/quantum/plugins/ryu/ryu_quantum_plugin.py", line 226, in update_port > port_binding.dpid, port_binding.port_no)) > InvalidInput: Invalid input for operation: invalid (datapath_id, port_no) requested (00002eab88ec5140, 4), but (0000c2f19014c74a, 1).
