So, a few questions...

 - If there are no users shall we remove it from Havana and Grizzly as
well, or does that violate our stability principles too much?

 - If we don't remove the code from stable, what about removing all
references from the stable docs and putting in a warning saying that
powervm is a dead end instead? I want to minimise confusion on the
part of people deploying stable releases.

 - And finally, as someone who spent a bunch of time reviewing powervm
code I will admit that I'm kind of annoyed right now. How can IBM
reassure us that powervc has customers asking for a driver, and that
those customers will actually deploy a driver if one is merged? Given
kvm for power is now announced and should be around in 2014, I'd much
prefer a powerkvm through libvirt implementation to minimise the
number of drivers.
