Hi there, I have 2 PC and each of them has 2 nics. One for internet access and another for internal network. I want to install havana with one controller and one compute. Neutron can be installed in any of them. The document illustrates 3 nics are needed for dedicated network node. Is there any articles for installing neutron service with only 2 nics? Any changes need to be performed based on http://docs.openstack.org/havana/install-guide/install/apt/content/? Thanks.
