      Waiting for the installer to finish. You may watch the progress via the EDIS Managemet interface at

        https://manage.edis.at/whmcs/clientarea.php?action=services

      Just go to the product page of the VM {{ install.cloud.id }} and enable VNC. After that you may use the
      built-in noVNC instance to watch the installer doing its thing.

      The installer will terminate the VM when done and the install process will continue automatically.
      If the installation is done quicker than this you may press ENTER to continue or CTRL-C then A to abort.
