The following sections describe many of the configuration option settings that can go into the
nova.conf files. Copies of each nova.conf file need
to be copied to each compute node. Here are some sample nova.conf
files that offer examples of specific configurations.
This example nova.conf file is from an
internal Rackspace test system used for demonstrations.
