[Openstack--Ansible] Playbook for Host Prep

Hello,

I am wondering if there is any sort of playbook or script for setting up the networking on a new physical host prior to adding it to a cluster. It is a bit cumbersome to do it by hand, especially given that bridges on one type of host need an IP while the same bridge on another type of host should not have an IP. Seeding the /etc/hosts file would be nice as well.

Going a bit further, it would be awfully nice if a given host could have the same 4th octet for all host interfaces, or at least for the important ones. I believe that since the 172.29 subnets are /22 this should be possible at least for smaller clusters.

Thanks.

-Dave
