So the symptoms you are showing me above almost definitely leads me to believe that neutron-server failed on the undercloud, which would explain why the deploy and nova failed to work. It could have failed before or during the deploy. We regularly see instances where neutron-server times out upon system boot (takes slightly longer to start than systemd expects), so we need to start it manually. To be clear, The undercloud has been installed using this repo http://buildlogs.centos.org/centos/7/cloud/x86_64/rdo-trunk-newton-tested/ Which overcloud images are you using? I'm not seeing any provided in that repo, and I just want to make sure the undercloud and overcloud packages match (as the tripleo-heat-templates package on the undercloud has to align with the openstack-puppet-modules package on the overcloud iamges). Also, is it possible to get a copy of all the neutron-server log from the undercloud? If we can understand why neutron-server failed, that is the first step towards getting a working deployment. It would be great if we could get a full sosreport with all the system logs, to check for other errors. I'm assuming there were no problems with the 'openstack undercloud install' process?
