I am running my cloud using openstack-ansible on centos 7.5 (on
Production) and 8.x (on Lab because centos 8 soon end of life, my
future plan is to migrate everything to ubuntu ).
Answer to your question is you have two way to configure networking using OSA
1. Use systemd-networkd here is the example -
2. Use package network-scripts (This is legacy way to configure
network on centOS /etc/sysconfig/network-scripts/* style) - You can
see example on my blog how to deploy OSA on centos -
