CloudSigma
**********

This datasource finds metadata and user data from the `CloudSigma`_ cloud
platform. Data transfer occurs through a virtual serial port of the
`CloudSigma`_'s VM, and the presence of a network adapter is **NOT** a
requirement. See `server context`_ in their public documentation for more
information.

Setting a hostname
==================

By default, the name of the server will be applied as a hostname on the first
boot.

Providing user data
-------------------

You can provide user data to the VM using the dedicated `meta field`_ in the
`server context`_ ``cloudinit-user-data``. By default, *cloud-config* format
is expected there, and the ``#cloud-config`` header can be omitted. However,
since this is a raw-text field you could provide any of the valid :ref:`config
formats<user_data_formats>`.

You have the option to encode your user data using Base64. In order to do that
you have to add the ``cloudinit-user-data`` field to the ``base64_fields``.
The latter is a comma-separated field with all the meta fields having
Base64-encoded values.

If your user data does not need an internet connection you can create a
`meta field`_ in the `server context`_ ``cloudinit-dsmode`` and set "local" as
the value. If this field does not exist, the default value is "net".
