Get images

The simplest way to obtain a virtual machine image that works with OpenStack is to download one that someone else has already created. Most of the images contain the cloud-init package to support the SSH key pair and user data injection. Because many of the images disable SSH password authentication by default, boot the image with an injected key pair. You can SSH into the instance with the private key and default login account. See the OpenStack End User Guide for more information on how to create and inject key pairs with OpenStack.

CentOS images

The CentOS project maintains official images for direct download.

Note

In a CentOS cloud image, the login account is centos.

CirrOS (test) images

CirrOS is a minimal Linux distribution that was designed for use as a test image on clouds such as OpenStack Compute. You can download a CirrOS image in various formats from the CirrOS download page.

If your deployment uses QEMU or KVM, we recommend using the images in qcow2 format. The most recent 64-bit qcow2 image as of this writing is cirros-0.3.4-x86_64-disk.img.

Note

In a CirrOS image, the login account is cirros. The password is cubswin:).

Official Ubuntu images

Canonical maintains an official set of Ubuntu-based images.

Images are arranged by Ubuntu release, and by image release date, with current being the most recent. For example, the page that contains the most recently built image for Ubuntu 14.04 Trusty Tahr is http://cloud-images.ubuntu.com/trusty/current/. Scroll to the bottom of the page for links to the images that can be downloaded directly.

If your deployment uses QEMU or KVM, we recommend using the images in qcow2 format. The most recent version of the 64-bit QCOW2 image for Ubuntu 14.04 is trusty-server-cloudimg-amd64-disk1.img <http://uec-images.ubuntu.com/ trusty/current/trusty-server-cloudimg-amd64-disk1.img>.

Note

In an Ubuntu cloud image, the login account is ubuntu.

Official Red Hat Enterprise Linux images

Red Hat maintains official Red Hat Enterprise Linux cloud images. A valid Red Hat Enterprise Linux subscription is required to download these images.

  • Red Hat Enterprise Linux 7 KVM Guest Image <https://access.redhat.com/ downloads/content/69/ver=/rhel---7/7.0/x86_64/product-downloads>
  • Red Hat Enterprise Linux 6 KVM Guest Image <https://rhn.redhat.com/ rhn/software/channel/downloads/Download.do?cid=16952>

Note

In a RHEL cloud image, the login account is cloud-user.

Official Fedora images

The Fedora project maintains a list of official cloud images at https://getfedora.org/en/cloud/download/.

Note

In a Fedora cloud image, the login account is fedora.

Official openSUSE and SLES images

SUSE provides images for openSUSE. For SUSE Linux Enterprise Server (SLES), custom images can be built with a web-based tool called SUSE Studio. SUSE Studio can also be used to build the custom openSUSE images.

Official Debian images

Since January 2015, Debian provides images for direct download. They are now made at the same time as the CD and DVD images of Debian. Therefore, images are available on each point release of Debian. Also, weekly images of the testing distribution are available.

If you wish to build your own images of Debian 7.0 (aka Wheezy, the old stable release of Debian), you can use the package which is used to build the official Debian images. It is named openstack-debian-images, and it provides a simple script for building them. This package is available in Debian Unstable, Debian Jessie, and through the wheezy-backports repositories. To produce a Wheezy image, simply run:

# build-openstack-debian-image -r wheezy

If building the image for Wheezy, packages like cloud-init, cloud-utils or cloud-initramfs-growroot will be pulled from wheezy-backports. Also, the current version of bootlogd in Wheezy does not support logging to multiple consoles, which is needed so that both the OpenStack Dashboard console and the nova console-log console works. However, a fixed version is available from the non-official GPLHost repository <http://archive.gplhost.com/debian/pool/juno-backports/ main/s/sysvinit/bootlogd_2.88dsf-41+deb7u2_amd64.deb>. To install it on top of the image, it is possible to use the --hook-script option of the build-openstack-debian-image script, with this kind of script as parameter:

#!/bin/sh

cp bootlogd_2.88dsf-41+deb7u2_amd64.deb ${BODI_CHROOT_PATH}
chroot ${BODI_CHROOT_PATH} dpkg -i bootlogd_2.88dsf-41+deb7u2_amd64.deb
rm ${BODI_CHROOT_PATH}/bootlogd_2.88dsf-41+deb7u2_amd64.deb

Note

In a Debian image, the login account is admin.

Official images from other Linux distributions

As of this writing, we are not aware of other distributions that provide images for download.

Microsoft Windows images

Cloudbase Solutions hosts an OpenStack Windows Server 2012 Standard Evaluation image that runs on Hyper-V, KVM, and XenServer/XCP.
