After sending the below request, adding an already existing OVS instance to the config tree, the error from karaf (below the request) appears. This exception does not happen if the controller is the connection initiator. Moreover this error is repeated whenever a QOS entry or a QUEUE entry is added to the config tree under the OVS node.
It appears that QOS and QUEUEs cannot be configured unless the controller is the connection initiator.
