Im trying to test deploying Openstack using Ansible into two node, just a controller node and the deployment node, This deployment follow the offical Openstack Ansible tutorial Im just using br-mgmt for my test to simplify the process. I deployed br-mgmt on both nodes here are the "interfaces" file and "open_user_config.yml" file My OS is Ubuntu 16.04 My Interfaces File:

     auto enp5s4f0
     iface enp5s4f0 inet manual
        bond-master bond0
        bond-primary enp5s4f0

    auto enp5s4f1
    iface enp5s4f1 inet manual
        bond-master bond0

    auto bond0
    iface bond0 inet manual
        bond-mode active-backup
        bond-miimon 100
        bond-slaves none
        bond-downdelay 200
        bond-updelay 200
