OpenNebula Cloud Module
=======================

The OpenNebula cloud module is used to control access to an OpenNebula cloud.

.. versionadded:: 2014.7.0

:depends: lxml
:depends: OpenNebula installation running version ``4.14`` or later.

Use of this module requires the ``xml_rpc``, ``user``, and ``password``
parameters to be set.

Set up the cloud configuration at ``/etc/salt/cloud.providers`` or
``/etc/salt/cloud.providers.d/opennebula.conf``:

.. code-block:: yaml

    my-opennebula-config:
      xml_rpc: http://localhost:2633/RPC2
      user: oneadmin
      password: JHGhgsayu32jsa
      driver: opennebula

This driver supports accessing new VM instances via DNS entry instead
of IP address.  To enable this feature, in the provider or profile file
add `fqdn_base` with a value matching the base of your fully-qualified
domain name.  Example:

.. code-block:: yaml

    my-opennebula-config:
      [...]
      fqdn_base: <my.basedomain.com>
      [...]

The driver will prepend the hostname to the fqdn_base and do a DNS lookup
to find the IP of the new VM.

.. note:

    Whenever ``data`` is provided as a kwarg to a function and the
    attribute=value syntax is used, the entire ``data`` value must be
    wrapped in single or double quotes. If the value given in the
    attribute=value data string contains multiple words, double quotes
    *must* be used for the value while the entire data string should
    be encapsulated in single quotes. Failing to do so will result in
    an error. Example:

.. code-block:: bash

    salt-cloud -f image_allocate opennebula datastore_name=default \\
        data='NAME="My New Image" DESCRIPTION="Description of the image." \\
        PATH=/home/one_user/images/image_name.img'
    salt-cloud -f secgroup_allocate opennebula \\
        data="Name = test RULE = [PROTOCOL = TCP, RULE_TYPE = inbound, \\
        RANGE = 1000:2000]"
