Cloud Init ISO Many premade cloud images (e.g. Fedora Cloud, Ubuntu Cloud) use some form of cloud-init to set instance/user metadata, such as hostnames and SSH keys. This works well when used in a cloud infrastructure such as EC2 or OpenStack that can seed this data, but not so well when used for local VMs, or an out-of-the-box XenServer. cloud-init is developed and released as free software under both the GPLv3 open source license and the Apache License version 2.0.
