Opendaylight stacktrace when creating open vswitch qos and queue

Question

I have an Opendaylight Carbon application that is running just fine. Now I want to add QoS and queues to it (Open vSwitch 2.5.2). If I create a qos using ovs-vsctl in a terminal, Opendaylight starts logging stack traces. The ovs-vsctl command:

sudo ovs-vsctl -- set port s1-eth1 qos=@newqos -- --id=@newqos create qos type=linux-htb other-config:max-rate=800000

The stack trace (only included the first few stack traces):

As it shows a ModifiedNodeDoesNotExistException, do I have to install some ovs related feature? If so, which one?

I assume that ODL gets notified of the qos and queue creation and tries to update the operational data store. The Exception complains that node

Node /(urn:opendaylight:inventory?revision=2013-08-19)nodes/node/node[{(urn:opendaylight:inventory?revision=2013-08-19)id=openflow:1}]/node-connector/node-connector[{(urn:opendaylight:inventory?revision=2013-08-19)id=1}]

does not exist. Why isn't this nodeconnector id=openflow:1:1 in stead of id=1?

Wireshark openflow shows that these exceptions are likely triggered by the OFPMP_QUEUE reply. If no queues, this message is empty. If queues exist (like example below, queue 0,1,2) it reports stats for queues on port 1:

OpenFlow 1.3
    Version: 1.3 (0x04)
    Type: OFPT_MULTIPART_REPLY (19)
    Length: 136
    Transaction ID: 5709
    Type: OFPMP_QUEUE (5)
    Flags: 0x0000
    Pad: 00000000
    Queue stats
        Port number: 1
        Queue ID: 0
        Tx bytes: 60
        Tx packets: 1
        Tx errors: 0
        Duration sec: 2954916689
        Duration nsec: 174000000
    Queue stats
    Queue stats

I assume that ODL fails to map port 1 to node-connector openflow:1:1. This probably causes the exception because node-connector 1 cannot be found.

This seems like a bug in ODL so I just opened a bug: https://jira.opendaylight.org/browse/OPNFLWPLUG-995 — ecelgp, Apr 06 '18 at 01:03

The problem is indeed that the controller is parsing the OFPMP_QUEUE reply and wants to write statistics to node-connector '1' in stead of 'openflow:1:1'. To test this hypothesis, I wrote my own node-connector '1' in the operational datastore, containing queue 0, 1 and 2. I adapted my application to use queues and as soon I created the queues with ovs-vsctl command in first post, everything works:

The node-connector '1' is updated with queue stats in the operational DS
Flows that use the queue are indeed limited by the max-rate of the queue

The question is now:

Is this a bug
OR do I actually have to do it this way
OR should I only use queues that are created through the OVSDB plugin of ODL?

I am developing from a maven ODL Carbon archetype and have not been able to get OVSDB support. The OVSDB does not (yet?) seem to exist as a plugin feature for the Carbon release.

Any help is appreciated.

These look like questions for [the OpenDaylight mailing list](https://lists.opendaylight.org/mailman/listinfo), maybe `openflowplugin-users`? — pchaigno, Dec 27 '17 at 12:28
