===========
AMT drivers
===========
Overview
========
AMT (Active Management Technology) drivers extend Ironic's range to the
desktop. AMT/vPro is widely used in desktops to remotely control their power,
similar to IPMI in servers.
AMT drivers use WS-MAN protocol to interact with AMT clients.
They work on AMT 7.0/8.0/9.0. AMT 7.0 was released in 2010, so AMT drivers
should work on most PCs with vPro.
There is one AMT driver:
* ``pxe_amt`` uses AMT for power management and PXE for deploy management.
Set up your environment
=======================
A detailed reference is available here, and a short guide follows below:
https://software.intel.com/en-us/articles/intel-active-management-technology-start-here-guide-intel-amt-9#4.2
* Set up AMT Client
* Choose a system which supports Intel AMT / vPro. Desktop and laptop systems
that support this can often be identified by looking at the "Intel" tag for
the word ``vPro``.
* During boot, press Ctrl+P to enter Intel MEBx management.
* Reset password -- default is ``admin``. The new password must contain at
least one upper case letter, one lower case letter, one digit and one
special character, and be at least eight characters.
* Go to Intel AMT Configuration:
* Enable all features under SOL/IDER/KVM section
* Select User Consent and choose None (No password is needed)
* Select Network Setup section and set IP
* Activate Network Access
* MEBx Exit
* Restart and enable PXE boot in bios
* Install ``openwsman`` on servers where ``ironic-conductor`` is running:
* Fedora/RHEL: ``openwsman-python`` (>=2.4.10). You can
get the RPM package for Fedora 20 from::
http://download.opensuse.org/repositories/Openwsman/Fedora_20/
* Ubuntu: ``python-openwsman``'s most recent version is 2.4.3 which
isn't recent enough, so you'll need to build it yourself (see next point)
* Or build it yourself from::
https://github.com/Openwsman/openwsman
* Enable the ``pxe_amt`` driver by adding it to the configuration option
``enabled_drivers`` (typically located at ``/etc/ironic/ironic.conf``)
and restart the ``ironic-conductor`` process::
service ironic-conductor restart
* Enroll an AMT node
* Specify these driver_info properties for the node: ``amt_password``,
``amt_address``, and ``amt_username``
* Boot an instance
.. note::
It is recommended that nodes using the pxe_amt driver be deployed with the
`local boot`_ option. This is because the AMT firmware currently has no
support for setting a persistent boot device. Nodes deployed without the
`local boot`_ option could fail to boot if they are restarted outside of
Ironic's control (I.E. rebooted by a local user) because the node will
not attempt to PXE / network boot the kernel, using `local boot`_ solves this
known issue.
