    Added support for `microversion 2.90`_. This microversion provides the
    ability to manually configure the instance ``hostname`` attribute when
    creating a new instance (``nova boot --hostname HOSTNAME ...``), updating
    an existing instance (``nova update --hostname HOSTNAME ...``), or
    rebuilding an existing instance (``nova rebuild --hostname HOSTNAME``).
    This attribute is published via the metadata service and config drive and
    can be used by init scripts such as ``cloud-init`` to configure the guest's
    hostname.
