Overview of nova.conf

The nova.conf configuration file is an INI file format as explained in ../config-format.

You can use a particular configuration option file by using the option (nova.conf) parameter when you run one of the nova-* services. This parameter inserts configuration option definitions from the specified configuration file name, which might be useful for debugging or performance tuning.

For a list of configuration options, see the tables in this guide.

To learn more about the nova.conf configuration file, review the general purpose configuration options documented in the table nova-common.

Important

Do not specify quotes around nova options.
