PowerVM¶

Usage¶

To make use of the PowerVM compute driver, a PowerVM system set up with NovaLink is required.

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.
