The nova-manage command

Introduction

The nova-manage command is used to perform many essential functions for administration and ongoing maintenance of nova, such as user creation, vpn management, and much more.

The standard pattern for executing a nova-manage command is:

nova-manage <category> <command> [<args>]

For example, to obtain a list of all projects:

nova-manage project list

You can run without arguments to see a list of available command categories:

nova-manage

You can run with a category argument to see a list of all commands in that category:

nova-manage user
