Hello to everyone

Resently i have setup an OpenStack cloud system and as a next target i would like to integrate OpenDaylight as the main networking controller. I tried to find information but everithing i found about this topic was integration of OpenDaylight with the use of DevStack which is not covering my case. Could someone plese give me some information or references about this issue

Best regards

Greetings rvatsparker Thank you very much for taking time reading my post and write a reply. It gave me some help It was also recommended to me by another source the following links which also gave me some help http://networkstatic.net/opendaylight-openstack-integration-devstack-fedora-20/ and http://www.siliconloons.com/opendaylight-integration-with-openstack-has-merged-into-icehouse/ But like i mention these links and the ones i had found while i was searching for a solution are about DEV Stack. I already have an installation of Openstack with Neutron made following the installation guide and i want on this installation to implement OpenDaylight. DEV Stack installation script will automatically install OpenStack and will automatically make the configuration needed for OpenDaylight but in the end what kind of configuration was made and on which files and nodes is obscure. Trying to combine the information i found i ended up with a solution that works but it is not completely

correct. Looking at OpenStack operations guide http://docs.openstack.org/openstack-ops/content/network_troubleshooting.html , Figure 12.2. Neutron network paths you will see that openstack creates a bridge br-int in order to build the networks for the VMs. Every VM instance, the DHCP agent and the L3-agent responsible for the rooting of networks, is connected on br-int bridge. I downloaded a precompiled version of Opendaylight, got into the configuration file and set the listening port on 6653 set the ip of the controller to 10.0.0.11 as i run the controller on control node, and set the openflow protocon to version 1.3. Then on every compute node and also on the network node i set the brige controller for br-int to be the opendaylight with the command ovs-vsctl set-controller br-int tcp:10.0.0.11:6653 . Now a am able to set flow records to the flow ...(more)

correct solution. If you have any suggestions to improve this i would be glad to talk about it.

Looking for an answer too. Opendaylight Helium integration with Openstack Juno RDO vxlan Centos 7.0 Managed to get it working .. for a while, after half an hour started getting ovsdb monitor errors and loss of conectivity on the VMs, not a single packet gets forwarded. Time to start over from snapshot...

Not sure if that was the source of problems but I added br-tun to ODL controller also. Got a beautiful topology showing br-int connected to br-tun...

Follow the wiki: https://wiki.opendaylight.org/view/OpenStackandOpenDaylight See if you can see neutron and compute nodes in dlux. Create a network and launch an instance. If its successful, then good. Otherwise run the following commands on both the nodes.

 ovs-vsctl get Open_vSwitch . _uuid It will return a uuid, lets call it uuid_returned.
 ovs-vsctl set Open_vSwitch <uuid_returned> other_config:local_ip=<ip-of-your-data-interface>

Data interface here refers to whichever interface you want data traffic to use.

This is if you are using GRE tunnelling. For more reference the solution is here: https://ask.opendaylight.org/question/2568/after-integrating-openstack-with-odl-vms-donot-get-ip/?answer=2613#post-id-2613

Keep posted..

That first link should likely be: https://wiki.opendaylight.org/view/OpenStack_and_OpenDaylight .
