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.
