Getting Images

The simplest way to obtain a virtual machine image that works with Metacloud is to download one that already exists. The following is a list of images available for download:

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 Metacloud Security for Instances for more information on how to create and inject key pairs.
