    <title>DESCRIPTION</title>

    <para>

      The <command>&dhpackage;</command> is the daemon which is

      responsible for the cluster functions in the ganeti system.

    </para>

    <para>

      For testing purposes, you can give the <option>-f</option>

      option and the program won't detach from the running terminal.

    </para>

    <refsect2>

      <title>ROLE</title>

      <para>

        The role of the node daemon is to do almost all the actions

        that change the state of the node. Things like creating disks

        for instances, activating disks, starting/stopping instance

        and so on are done via the node daemon.

      </para>

      <para>

        If the node daemon is stopped, the instances are not affected,

        but the master won't be able to talk to that node.

      </para>

    </refsect2>

    <refsect2>

      <title>COMMUNICATION PROTOCOL</title>

      <para>

        Currently the master-node protocol is done using the Twisted

        perspective broker libraries.

      </para>
