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.
