Ultimate OpenStack IceHouse Guide

This is a Quick Guide to deploy OpenStack IceHouse on top of Ubuntu 14.04, it is IPv6-Ready!

It is compliant with OpenStack's official documentation (docs.openstack.org).

The tenant's subnets are based on Neutron, with ML2 plugin and Single Flat Network topology, dual-stacked.

The Single Flat Network is the simplest network topology supported by OpenStack (I think). So, it is easier to understand and follow.
