[Rdo-list] Packstack Juno with existing external network?

[Patrick Laimbock]

Hi,

Setup: workstation with F20 + libvirt/kvm (nested virt enabled) and 
several VMs like MariaDB Galera cluster VMs, HAProxy VMs, OpenLDAP 
cluster VMs, RabbitMQ cluster VMs etc. Each VM gets assigned an IP 
address via DHCP in the 10.0.0.0/24 range.

Goal: packstack to create 1 Controller node and 2 Compute nodes (Juno) 
on 3 freshly provisioned CentOS 7 VMs. The Cirros instance on any of the 
2 Compute nodes should have Internet access and it should be possible to 
access the Cirros instance on its floating IP from the local 10.0.0.0/24 
network.

I just read:
https://openstack.redhat.com/Neutron_with_existing_external_network

and was wondering if there is a way I can get that setup pre-defined in 
a packstack answer file? If yes, any suggestions which vars need to be 
defined?

Thanks,
Patrick
