Comment 1 for bug 1761722

What is the correct solution? I try to roll out an Openstack-Ansible rocky Production Ceph envoirement(10hosts - one is a seperated deployment-host). So far just problems :(

i tryed to follow the instructions closely, but can't manage to get it running.

When i leave out the part about the veth-pairing in network config, i can execute the playbooks successfully(all 3). But in Horizon i cannot manage the networks... - the neutron-linuxbridge-agenst crashes and reboots every 5s seconds on the infra-nodes... error is a missing interface eth12

if i uncomment the part about veth-pairs the interface eth12 gets created and the neutron-linuxbridge-agent starts at least and keeps running. But in this configuration i cannot execute the playbooks succsessfully anymore... it crashes because the containers cannot update the apt-cache anymore :(

can anybody explain to us, what is the correct config? Is the veth-pair needed on infrastructure-nodes?
i followed this: https://docs.openstack.org/openstack-ansible/rocky/user/ceph/full-deploy.html
