Let me point out some details on this.

IBM's strategic direction is to invest in PowerVC [1] and is developing 
blueprints for review in Icehouse to work with the PowerVC 
virtualization manager, similar to VMware's approach with integration 
of vCenter with OpenStack.  That includes CI support.

Given the deprecation plan [2] we can follow that schedule as we work 
with the community to get support on how best to support IBM's PowerVM 
hypervisor through the strategic path.

We are interested in your thoughts on how to best proceed to make this 
an effective transition to the strategic PowerVC driver.
