Deployment Models
• PowerVC
– Provides support, a streamlined experience, and a lot of value add…
specific to POWER servers
• OpenStack Ansible (OSA)
– Provides Ansible playbooks and roles for the deployment and configuration
of an OpenStack environment
• Download and configure manually
– Add PowerVM support to your existing OpenStack cloud without Ansible
• DevStack
– A series of extensible scripts used to quickly bring up a complete
OpenStack environment for development & testing

Continuous Integration
Every proposed Nova code change is tested by the PowerVM CI
– ”Every” means every… not only changes related to PowerVM
– Tested with both in-tree (nova) and out-of-tree (nova-powervm) drivers
– Helps catch issues before changes are accepted
– Required by the nova core team
