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.

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:).

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.

Scroll to the bottom of the page for links to the images that can be downloaded directly.
