Bug Description

Operating system distribution and version: CentOS 7.6.1810
Kolla-Ansible package version: 8.0.0.0rc1
install_type (source/binary) and distribution from /etc/kolla/globals.yml: stein source
Are you using official images from Docker Hub or self built? Official

nova.conf currently uses the deprecated url= [neutron] option:

https://opendev.org/openstack/kolla-ansible/src/branch/stable/stein/ansible/roles/nova/templates/nova.conf.j2#L142

It looks like it was deprecated in Queens in favor of endpoint lookup in the catalog:
https://docs.openstack.org/nova/stein/configuration/config.html#neutron.url

This works fine if you only have a single region but in a multiple region environment it can cause Nova to use the wrong region. In particular I discovered this while live migrating and it failed to find the port on the destination server.

The fix I confirmed that works is to simply add an override to specify the region name:

/etc/kolla/config/nova.conf:
[neutron]
region_name = {{region_name}}

Before fix:
(openstack) server migrate --live node1 --wait e9002be1-d531-40e2-8583-fb276983996a
Migration pre-check error: Binding failed for port 6d477b7f-310f-4a6c-8a6a-12eb6d53fa1d, please check neutron logs for more information. (HTTP 400) (Request-ID: req-7d29c01f-fbf4-406d-aede-f3f45fd6e62c)

After fix:
(openstack) server migrate --live node2 --wait e9002be1-d531-40e2-8583-fb276983996a
Complete

Ideally the [neutron] section would be updated to specify all the the endpoint lookup options to match other Kolla service configurations.

    [nova] Fix service catalog lookup of Neutron endpoint

    nova.conf currently uses the [neutron] "url" parameter which has been
    deprecated since 17.0.0. In multi-region environments this can
    cause Nova to look up the Neutron endpoint for a different region.
    Remove this parameter and set region_name and
    valid_interfaces to allow the correct lookup to be performed.
