When you are creating a new VM a Cloud-init file can be used to describe how the VM is to be configured after the selected image has been loaded. CloudInit files can be used with the Horizon dashboard (OpenStack's web GUI), the CLI, or the Python API. Here we describe how to use a CloudIinit file with Horizon. | ||
