<title>Enabling Networking</title>
|
|
|
|
<para>Configuring Networking can be one of the most bewildering experiences
|
|
you will encounter when working with OpenStack. To assist in this we have
|
|
chosen the simplest production-ready configuration for this guide: the legacy
|
|
networking in OpenStack Compute, with a flat network, that takes care of DHCP
|
|
and is made highly available by splitting across multiple hosts.</para>
|
|
<note><para>If you require the full software-defined networking stack, see <link
|
|
linkend="ch_neutron">Using Neutron Networking</link>.</para></note>

|
<procedure>
|
|
<step><para>After performing initial configuration of the compute node,
|
|
install the appropriate packages for compute networking.</para>
