Overview of nova.conf
The nova.conf
configuration file is an
INI file format
as explained in Configuration file 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.
Important
Do not specify quotes around nova options.
