powervm: drop support 

The PowerVM driver has been untested for a few years as well
as broken due to using the wrong driver as well.  It's not possible
to test it within our infrastructure neither has there been any
contributions to improve/fix it.

This patch drops the support for it.

`Home <index.html>`_ OpenStack-Ansible Neutron
=====================================
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.
.. _NovaLink: http://www.ibm.com/support/knowledgecenter/POWER8/p8eig/p8eig_kickoff.htm?cp=POWER8
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 ``nova-powervm`` usage_.
.. _usage: http://nova-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
nova_nova_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
nova_nova_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
``nova_console_type`` variable to enable NoVNC:
.. code-block:: yaml
nova_console_type: novnc
Enabling configuration drive
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
By default, PowerVM uses configuration drives to provide configuration
information to instances built by nova. To enable this support in
OpenStack-Ansible, you can set the ``nova_force_config_drive``
variable as documented in the `nova configuration instructions`_.
.. _nova configuration instructions: ./configure-nova.html#config-drive
Additionally, you can enable flat network injection by using the
``nova_nova_conf_overrides`` variable:
.. code-block:: yaml
nova_nova_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 ``nova_nova_conf_overrides`` variable:
.. code-block:: yaml
nova_nova_conf_overrides:
DEFAULT:
use_ipv6: True
.. _RMC: http://www.ibm.com/support/knowledgecenter/8284-22A/p8eig/p8eig_rmc.htm

The driver type is automatically detected by the OpenStack Ansible Nova role
for the following compute driver types:
- libvirt (kvm / qemu)
- powervm
Any mix and match of compute node types can be used for those platforms,
except for ironic.

deprecations:
- The PowerVM driver has been removed as it is not tested and
it has been broken since late 2016 due to the driver name
being renamed to powervm_ext instead of powervm.
