Boot McKernel
----------------

A boot script called ``mcreboot.sh`` is provided under ``sbin`` in the install
folder. To boot on logical CPU 1 with 512MB of memory, use the following
invocation:

::

   export TOP=${HOME}/ihk+mckernel/
   cd ${TOP}
   sudo ./sbin/mcreboot.sh -c 1 -m 512m

You should see something similar like this if you display the McKernel’s
kernel message log:

.. code-block:: none

   ./sbin/ihkosctl 0 kmsg

Run a simple program on McKernel
-----------------------------------

The mcexec command line tool (which is also the Linux proxy process) can
be used for executing applications on McKernel:

::

   ./bin/mcexec hostname
   centos-vm

Shutdown McKernel
--------------------

Finally, to shutdown McKernel and release CPU/memory resources back to
Linux use the following command:

::

   sudo ./sbin/mcstop+release.sh
