Usage
|
|
-----
|
|
To make use of the PowerVM compute driver, a PowerVM system set up with
|
|
`NovaLink`_ is required.
|
|
|
|
.. _NovaLink: https://www.ibm.com/support/knowledgecenter/en/POWER8/p8eig/p8eig_kickoff.htm
|
|
|
|
Installing the NovaLink software creates the ``pvm_admin`` group. In
|
|
order to function properly, the user executing the Nova compute service must
|
|
be a member of this group. Use the ``usermod`` command to add the user. For
|
|
example, to add the user ``stacker`` to the ``pvm_admin`` group, execute::
|
|
|
|
sudo usermod -a -G pvm_admin stacker
|
|
|
|
The user must re-login for the change to take effect.
|
|
|
|
The NovaLink architecture is such that the compute driver runs directly on the
|
|
PowerVM system. No external management element (e.g. Hardware Management
|
|
Console or PowerVC) is needed. Management of the virtualization is driven
|
|
through a thin virtual machine running on the PowerVM system.
|
|
|
|
Configuration of the PowerVM system and NovaLink is required ahead of time. If
|
|
the operator is using volumes or Shared Storage Pools, they are required to be
|
|
configured ahead of time.
|
|
|
|
|
|
Configuration File Options
|
|
--------------------------
|
|
After nova has been installed the user must enable PowerVM as the compute
|
|
driver. To do so, set the ``compute_driver`` value in the ``nova.conf`` file
|
|
to ``compute_driver = powervm.driver.PowerVMDriver``.
