Hi everyone! this is my first time on a mailing list, so please excuse any "obvious" mistakes and feel free to correct me :) I'm currently setting up a minimal OpenStack system manually on one server. The setup is nearly complete but I'm running into issues with neutron. After fully completing the neutron setup as mentioned in the docs, the neutron-ovs-service refuses to start, showing the error message multiple rows in Manager patch "ptcp:6640:127.0.0.0" I dumped the ovs database which only shows one row in the Manager table. After many days of debugging and googleing I'm out of ideas how this could be solved.. I already posted this issue on serverfault (https://serverfault.com/questions/1160418/openstack-ovs-multiple-rows-in-man...), only after that post finding this mailing list! Best regards Talooola
