=====================================
|
|
Scenario - Using PowerVM Nova plugin
|
|
=====================================
|
|
|
|
Prerequisites
|
|
~~~~~~~~~~~~~
|
|
|
|
In order to use the PowerVM OpenStack drivers with OpenStack-Ansible (OSA), the
|
|
following pre-requisites must be fulfilled:
|
|
|
|
- At least one of the repo-build servers must be ppc64le. Can mix and match
|
|
repo-build servers between x86 and ppc64le.
|
|
|
|
- The compute nodes should be pre-configured for PowerVM with the NovaLink_
|
|
feature.
|
|
|
|
- The NovaLink Management VM needs at least one direct attach I/O card.
|
|
OpenStack Ansible is currently able to deploy the PowerVM drivers when
|
|
paired with the Open vSwitch agent. The traditional PowerVM Shared Ethernet
|
|
Adapter networking agent is not yet supported.
|
|
|
|
- The network topology on the NovaLink must match a supported OpenStack
|
|
Ansible network configuration.

|
PowerVM usage
|
|
~~~~~~~~~~~~~
|
|
|
|
The Compute driver for OpenStack-Ansible should automatically detect that it
|
|
is of type PowerVM. If the user has specified a specific compute type, that
|
|
is applicable to the whole cloud. It is advised that the you allow OSA to
|
|
detect the appropriate compute node type.
|
|
|
|
The full set of configuration options for the PowerVM driver can be
|
|
found in the ``zun-powervm`` usage_.
|
|
|
|
.. _usage: https://zun-powervm.readthedocs.io/en/latest/devref/usage.html
|
|
|
|
|
|
Configuring storage
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
There are various storage back ends available for PowerVM such as local disk
|
|
and shared storage pools. For example, to enable local disk storage backed by
|
|
a logical volume group, you can set:
|
|
|
|
.. code-block:: yaml
|
|
|
|
zun_zun_conf_overrides:
|
|
powervm:
|
|
disk_driver: localdisk
|
|
volume_group_name: <<VOLUME GROUP NAME>>
|
|
|
|
To enable iSCSI as the volume attachment type, you can set the
|
|
``volume_adapter`` setting:
|
|
|
|
.. code-block:: yaml
|
|
|
|
zun_zun_conf_overrides:
|
|
powervm:
|
|
volume_adapter: iscsi
|
|
|
|
The default volume attachment type for PowerVM is fibre channel.
|
|
|
|
Enabling VNC console
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
PowerVM only supports connecting to instance consoles over VNC. As
|
|
OpenStack-Ansible defaults to Spice console, you must set the
|
|
``zun_console_type`` variable to enable NoVNC:
|
|
|
|
.. code-block:: yaml
|
|
|
|
zun_console_type: novnc
|
|
|
|
|
|
Enabling configuration drive
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
By default, PowerVM uses configuration drives to provide configuration
|
|
information to instances built by zun. To enable this support in
|
|
OpenStack-Ansible, you can set the ``zun_force_config_drive``
|
|
variable as documented in the `zun configuration instructions`_.
|
|
|
|
.. _zun configuration instructions: ./configure-zun.html#config-drive
|
|
|
|
Additionally, you can enable flat network injection by using the
|
|
``zun_zun_conf_overrides`` variable:
|
|
|
|
.. code-block:: yaml
|
|
|
|
zun_zun_conf_overrides:
|
|
DEFAULT:
|
|
flat_injected: True
|
|
|
|
Enabling PowerVM RMC
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
To enable PowerVM RMC_, IPv4/IPv6 dual-stack mode must be enabled. To do this,
|
|
you must set ``use_ipv6`` using the ``zun_zun_conf_overrides`` variable:
|
|
|
|
.. code-block:: yaml
|
|
|
|
zun_zun_conf_overrides:
|
|
DEFAULT:
|
|
use_ipv6: True
|
|
|
|
