This feature was added in v9.1 of the Scale Product.

These are examples how to pass cloudInitData on VM clone, which can also be done on VM Import and VM Create as well.

In order to pass cloud-init customization:

* Base64 encode these values
* Pass the base64 encoded values in the `cloudInitData` parameter
  available to VM Create, Clone, or Import.
