The fourth (4) step of 'Configure networking' in the 'Configure Compute services' chapter (RHEL, CentOS, Fedora), says: start the network service, but in the command of the step it restarts the network service. This results to a warning that the openstack-nova-network service was not able to stop. This commit just changes the argument of the service command to start.

<title>Configure networking</title>
|
|
<para>Configuring networking in OpenStack can be a bewildering experience. The
|
|
following example shows the simplest production-ready
|
|
configuration that is available: the legacy networking in
|
|
OpenStack Compute, with a flat network, that takes care of
|
|
DHCP.</para>
|
|
<para>This set up uses multi-host functionality. Networking is
|
|
configured to be highly available by distributing networking
|
|
functionality across multiple hosts. As a result, no single
|
|
network controller acts as a single point of failure. This process
|
|
configures each compute node for networking.</para>
