      The <command>VBoxManage startvm</command> command starts an

            You can use the <command>VBoxManage setproperty</command>
            command to set a global default value for the frontend.
            Alternatively, you can use the <command>VBoxManage
            modifyvm</command> command to specify a default frontend
            value for a specific VM. If neither a global or per-VM
            default value is set and you do not specify the
            <option>--type</option> option, then the VM opens in a
            window on the host desktop.

      <para>
        If a VM fails to start with a particular frontend and the error
        information is inconclusive, consider starting the VM directly
        by running the frontend. This workaround might provide
        additional error information.
