Description:

def secgroup_info(call=None, kwargs=None):
    '''
    Retrieves information for the given security group. Either a name or a
    secgroup_id must be supplied.

    .. versionadded:: 2016.3.0

    name
        The name of the security group for which to gather information. Can be
        used instead of ``secgroup_id``.

    secgroup_id
        The ID of the security group for which to gather information. Can be
        used instead of ``name``.

    CLI Example:

    .. code-block:: bash

        salt-cloud -f secgroup_info opennebula name=my-secgroup
        salt-cloud --function secgroup_info opennebula secgroup_id=5
