Synopsis
========

  nova-rootwrap [options]

Description
===========

`nova-rootwrap` is an application that filters which commands nova is allowed
to run as another user.

To use this, you should set the following in nova.conf::

  rootwrap_config=/etc/nova/rootwrap.conf

You also need to let the nova user run nova-rootwrap as root in sudoers::

  nova ALL = (root) NOPASSWD: /usr/bin/nova-rootwrap /etc/nova/rootwrap.conf *

To make allowed commands node-specific, your packaging should only install
{compute,network}.filters respectively on compute and network nodes, i.e.
`nova-api` nodes should not have any of those files installed.

.. note::

   `nova-rootwrap` is being slowly deprecated and replaced by `oslo.privsep`,
   and will eventually be removed.
