Before Neutron can be utilized as the network manager for OpenStack Compute services, the appropriate configuration options must be set in the Nova configuration file located at /etc/nova/nova.conf on certain hosts.

On the controller and compute nodes, update the [neutron] section with the following:

[neutron]  
... 
url= http://controller01:9696
auth_url = http://controller01:35357
auth_type = password 
project_domain_name = default 
user_domain_name = default 
region_name = RegionOne 
project_name = service 
username = neutron 
password = neutron 

Nova may require additional configuration once a Mechanism driver has been determined. The Linux bridge and Open vSwitch Mechanism drivers and their respective agents and Nova configuration changes will be discussed in further detail in upcoming chapters.
