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.
