I updated the networking content as follows: 1) Reordered example architectures to place the 3-node neutron architecture before the 2-node nova-network architecture which agrees with the order presented in other portions of the installation guide. 2) Changed network service naming to agree with conventions. 3) Permanently unlinked the Open vSwitch (OVS) plug-in sections from the Networking chapter. However, I will refrain from deleting the associated files in case we need to restore them. 4) Temporarily unlinked the Open vSwitch (OVS) portion of the Neutron concepts section until we can update it to reflect the Modular Layer 2 (ML2) plug-in. 5) Addressed other minor issues.

<para>After installing the operating system on each node for the

|
architecture that you choose to deploy, you must configure the network
|
|
interfaces. We recommend that you disable any automated network
|
|
management tools and manually edit the appropriate configuration files
|
|
for your distribution. For more information on how to configure networking

on your distribution, see the
