OpenStack Icehouse Installation: Two-node architecture with legacy networking (nova-network)

This document provides instructions on how to install and configure OpenStack icehouse on Ubuntu 14.04. Here we consider a two-node architecture with legacy networking. It's a simple and easily deployable architecture that requires two node types:

• Controller Node that runs management services (keystone, Horizon…) needed for OpenStack to function.
• Compute Node that runs the virtual machine instances in OpenStack.

We have deployed a single compute node (see the Figure below) but you can simply add more compute nodes, if needed.

Unlike our previous manual, in which we considered a multi-node architecture with Openstack Networking (Neutron), this manual details how to deploy OpenStack using a flat networking model.
The Installation guide is available here OpenStack-Icehouse-Installation-Nova-Network.
