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 wheezyIf 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.debNote
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.
