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 are two AMT drivers:
|
|
|
|
* ``pxe_amt_iscsi`` uses AMT for power management and deploys the user image
|
|
over iSCSI from the conductor.
|
|
|
|
* ``pxe_amt_agent`` uses AMT for power management and deploys the user image
|
|
directly to the node via HTTP.
|
|
|
|
Set up your environment
|
|
=======================
|
|
A detailed reference is available in `Intel Active Management Technology <https://software.intel.com/en-us/articles/intel-active-management-technology-start-here-guide-intel-amt-9#4.2>`_.
|
|
|
|
A short guide follows below:
|
|
|
|
* 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``.
|
|
|
|
* Ubuntu: ``python-openwsman``'s most recent version is 2.4.3 which
|
|
is enough.
|
|
|
|
* Or build it yourself from: https://github.com/Openwsman/openwsman
|
|
|
|
* Enable the ``pxe_amt_iscsi`` or ``pxe_amt_agent`` 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.
