Open Stack

Thanks, but yet another different error now.  Seems to be this:

	.ml2.drivers.openvswitch.agent.ovs_neutron_agent [-] No datapath_id on bridge br-int Agent terminated!: RuntimeError: No datapath_id on bridge br-int

Tearing my hair out here.

Yep, you found the right patch. That is a known issue right now and we should hopefully have the fix merged very shortly.

In the meantime, you could add this to your local.conf:

CINDER_BRANCH=refs/changes/46/626146/3

With that, devstack will pull down that version of the code and you should be able to get by this failure until we merge the fix. As of this moment, there is just a pep8 error that is preventing that from merging. That will not impact the ability to actually run the code.

Once that merges you can take that line out of the local.conf file to just get the current code from master.

Hope that helps.
