    I wonder whether the previous hostname was associated with the
    instance name or not. If yes, then your cloud-init worked, just that
    metadata was not updated by changing the instance name. If no, you
    need cloud-init built in the image and it will poll the metadata
    after reboot.<div><div class="h5"><br>
