    + * With the z/VM CP interface you can issue z/VM CP commands from a Linux

    + * the z/VM hypervisor, the z/VM CP interface does not provide any useful
    + * function and the corresponding vmcp device driver cannot be loaded.
    + * User action:
    + * Load the vmcp device driver only on Linux instances that run as guest
    + * operating systems of the z/VM hypervisor. If the device driver has been
    + * compiled into the kernel, ignore this message.
