3.15. Example nova.conf configuration files
The following sections describe the configuration options in the
nova.conf file. You must copy the nova.conf file to each compute node. The sample nova.conf files show examples of specific configurations.
Small, private cloud
This example
nova.conf file configures a small private cloud with cloud controller services, database server, and messaging server on the same server. In this case, CONTROLLER_IP represents the IP address of a central server, BRIDGE_INTERFACE represents the bridge such as br100, the NETWORK_INTERFACE represents an interface to your VLAN setup, and passwords are represented as DB_PASSWORD_COMPUTE for your Compute (nova) database password, and RABBIT PASSWORD represents the password to your message queue installation.
