Comment 1 for bug 1980226

Hi Peter.

I believe you end up with that error as there's some mis-configuration in openstack_user_config.yml
As you rightfully mentioned, according to https://docs.openstack.org/openstack-ansible-os_octavia/victoria/configure-octavia.html#vlan-networking-scenario you need to describe networks that are mapped to the container. In the example, one of the keys is `ip_from_q: "lbaas"`. Also, you should define lbaas network netmask in cidr_networks.

It would be helpful to debug if you also provided your configuration, as without it it's hard to understand what exactly went wrong with Octavia setup.
