Flags and Flagfiles
===================

Nova uses a configuration file containing flags located in
``/etc/nova/nova.conf``. You can get the most recent listing of avaialble
flags by running ``nova-(servicename) --help``, for example:

::

  nova-api --help

A script for generating a sample ``nova.conf`` file is located in
``<nova_root>/tools/conf/run.sh``. This script traverses through the
source code and retrieves information of every option that is
defined. A file named ``nova.conf.sample`` will be placed in the same
directory.

The OpenStack wiki has a page with the flags listed by their purpose
and use at http://wiki.openstack.org/FlagsGrouping.
