Hi everyone!

I want to integrate Helium release of OpenDaylight with OpenStack Kilo. I am using DevStack with local.conf that is described in this GitHub repository.

If I use master branch of devstack and NEUTRONCREATEINITIAL_NETWORKS=True, the following error is displayed:

It show that a port cannot be deleted directly via the port API (has device owner network:router_interface). I don't know how to fix this.

If I use stable/kilo branch of devstack and NEUTRONCREATEINITIAL_NETWORKS=True, OpenStack start correctly, and I can see the initial networks in topology, but when I aggregate some instance, then I can't see the network topology and I cannot access to instance consoles.

Anyone know how to fix this problem?

Thanks in advance.

I haven't tested the kilo script on master yet and expect it to require some changes. Since master on openstack is always changing it is hard to keep track of changes. Still, I'll try it out and add one for master.

Could you clarify what you mean 'aggregate' instances?

Yes, I suppose that master branch has a lot of changes and it isn't very stable to test with ODL. With aggregate instances, I mean launch new instances (virtual machines) with cirros for example. But now, I don't know if the problem is ODL or or some issue of OpenStack because only with Neutron (without ODL), I have the same problem.. :S I need to test again cleaning repositories.

Are you using same setup [VM?] for kilo and master? I use different setups for different branches, esp with devstack. Dependencies vary across branches and often cause one problem or another.

Yes, I am using the same VM, and to change the branch I do unstack.sh and git checkout to the other branch. You are right, it is better to use diferents VM, I do it! Thanks.

To fix this problem it is necessary to enable the service n-cauth, so in the local.conf we must add the line:

enable_service n-caut

Anyway, as Vishal says, it is better to use different setups for different branches.
