Hi everyone,

After successfully integrating ODL Helium SR3 with Openstack Juno, I want to give Lithium a try to see if some of the issues were fixed. I have setup Lithium in the same way as Helium, installing the following features:

opendaylight-user@root> feature:install odl-base-all odl-aaa-authn odl-restconf \
odl-nsf-all odl-adsal-northbound odl-mdsal-apidocs \
odl-ovsdb-openstack odl-ovsdb-northbound odl-dlux-core

This is per the instructions found along with Lithium archive on the download site: (one thing to note is that this document is actually created for Helium SR2)

But something is not working as expected. When I connect an Openstack node to ODL, by:

ovs-vsctl set-manager tcp:${CONTROL_HOST}:6640

I do not see 'br-int' created. Looking at Karaf logs (TRACE enabled on ovsdb) I only see this when a node is found:

2015-07-01 15:03:12,115 | INFO  | entLoopGroup-7-1 | LoggingHandler                   | 150 - io.netty.common - 4.0.26.Final | [id: 0xb2b4a22b, /0:0:0:0:0:0:0:0:6640] RECEIVED: [id: 0xac78804e, / => /]

I could see a lot more in Helium showing 'br-int' was created and default pipeline flows installed. Also DLUX interface shows only a blank topology screen.

Does anyone know if I am missing some features ? Has anything changed in Lithium in the way it integrates with Openstack ?

Thank you !

The feature list in the doc has changed. For Lithium all you need to install is the odl-ovsdb-openstack feature. Ignore all the other features listed in that long install command.

Thank you @shague after removing odl-ovsdb-northbound feature, integration seems to work.

As per @shague comment: "For Lithium all you need to install is the odl-ovsdb-openstack feature. "

Many thanks @shague for clarifying this. I also found some useful information in the Lithium Integration Test wiki page: Incompatibilities

It would be nice to have the doc updated for Lithium.

I have reached the stage where I could see some flows in br-int.

But while spwanning the vm in openstack its throwing an error saying

No Host found


When I checked the vxlan tunnels are not created though the openstack sends a VM update request to ODL.

POC Info:

  1. Integrating Juno-Lithium
  2. Used puppet to install openstack
  3. 4 node setup : 1controller,1network,1compute,1ODL
  4. ovs version is 2.0.2
  5. However "curl -u admin:admin http://${CONTROL_HOST}:8080/controller/nb/v2/neutron/ networks" returns { "networks" : [ ] }

What am I missing here. Is this again has anything to do with Lithium? Please help me out.

Now I am able to spwan the VM successfully. But it is not getting ip and still Sending Discoverry... vxlan tunnels are not created. What am I missing?

After upgrading ovs to 2.3.0, the vxlan tunnels are getting created. Thanks to Vishal Thapar.

Hi, I didn't use the setup with VXLAN, only GRE so far. I was about to ask if you checked /var/log/openvswitch/ovs-vswitchd.log for any errors. Do you know what the problem was in older OVS and how 2.3.0 fixed it ? Thank you !
