Public bug reported: Setting up one external flat network works fine. However when trying to setup more than one external flat network, neutron-openvswitch-agent disconnects ovs continously. This bug will be opened in both kolla and neutron since it is not determined what is causing this.
ENV: kolla stable/newton; containers are centos source. --------- relevant kolla config settings -------------------- /etc/kolla/globals.yml neutron_bridge_name: "br-vlan802,br-vlan805" neutron_external_interface: "bond0.802,bond0.805" #no dvr, lbaas, qos, etc ------------------------------------------------------------- config files and logs can be found here http://paste.openstack.org/show/589464/ http://paste.openstack.org/show/589286/ http://paste.openstack.org/show/589276/ snipplet from ovs log. 805 and 802 are the external bridges.
