DevStack - an OpenStack Community Production


Quick Start

  1. Select a Linux Distribution

    Only Ubuntu 14.04 (Trusty), Fedora 21 (or Fedora 22) and CentOS/RHEL 7 are documented here. OpenStack also runs and is packaged on other flavors of Linux such as OpenSUSE and Debian.

  2. Install Selected OS

    In order to correctly install all the dependencies, we assume a specific minimal version of the supported distributions to make it as easy as possible. We recommend using a minimal install of Ubuntu or Fedora server in a VM if this is your first time.

  3. Download DevStack

    git clone

    The devstack repo contains a script that installs OpenStack and templates for configuration files

  4. Configure

    We recommend at least a Minimal Configuration be set up.

  5. Start the install

    cd devstack; ./

    It takes a few minutes, we recommend reading the script while it is building.


Walk through various setups used by stackers

All-In-One Single VM

Run OpenStack in a VM. The VMs launched in your cloud will be slow as they are running in QEMU (emulation), but it is useful if you don’t have spare hardware laying around. [Read]

All-In-One Single Machine

Run OpenStack on dedicated hardware This can include a server-class machine or a laptop at home. [Read]

Multi-Node Lab

Setup a multi-node cluster with dedicated VLANs for VMs & Management. [Read]

DevStack with Neutron Networking

Building a DevStack cluster with Neutron Networking. This guide is meant for building lab environments with a dedicated control node and multiple compute nodes.

DevStack with KVM-based Nested Virtualization

Procedure to setup DevStack with KVM-based Nested Virtualization. With this setup, Nova instances will be more performant than with plain QEMU emulation.
