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.
The staging-amt
hardware type uses AMT for power and boot device
management.
Set up your environment¶
A detailed reference is available in Intel Active Management Technology.
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 whereironic-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
staging-amt
hardware type, power, deploy and management interfaces, for example:[DEFAULT] enabled_hardware_types = staging-amt,ipmi enabled_deploy_interfaces = direct enabled_management_interfaces = staging-amt,ipmitool enabled_power_interfaces = staging-amt,ipmitool
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
, andamt_username
- Specify these driver_info properties for the node:
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.
