> The three projects that PowerVMStackers contains (nova-powervm, networking-powervm, and ceilometer-powervm) are drivers/agents for nova, neutron, and ceilometer. They should ideally be under the umbrella of those projects, as other drivers/agents are, rather than split out as a PowerVMStackers project or SIG. But sadly, that is not the case due to historical reasons (primarily, the nova cores would not allow the nova powervm driver to be developed within nova like the drivers for Hyper-V, VMware, etc. so we had to create nova-powervm separately to do that development). I assure you that I've never liked that false dichotomy, but it was not our choice. The right thing to do here is to get them under those umbrellas, not to convert PowerVMStackers to a SIG. They need to be developed and managed just like any other OpenStack project producing code... not a SIG.
SIGs can produce code. The difference with project teams is that our
project teams are organized around a specific component (Nova, Swift...)
or a horizontal software development function that applies to all those
components (QA, Documentation, release management, common libraries...)
Once you frame it like that, you can spot a few outliers in the current
project team list: things that are neither centered around a specific
component nor a horizontal function: PowerVMStackers and Winstackers.
That said, I understand your objection. Establishing PowerVMStackers as
a SIG clearly sends the message that caring about PowerVM is a special
interest and not everyone's interest. It makes it less likely that the
*-powervm repository/features ever get merged into their respective
projects. And if this merging is right around the corner, I agree that
setting up a PowerVM SIG is counterproductive.
So I guess the real question is, is PowerVM support a mainline feature
that just happens to be temporarily maintained under a specific team for
weird organizational reasons ? Or is it considered not to be mainline
material (a bit like Windows support), and therefore the people that
care about that feature should maintain code to support that
indefinitely on the side ?
If it's the former, and there is a clear plan to get all that
functionality up in their respective teams in a near future, then I
agree a SIG won't really help. If the latter though, I really think that
a SIG is a much better way to represent what is happening there, and
would give the "PowerVM support" SIG extra visibility.
My impression is that it's been 4 years now that those repositories
exist separately from Nova, Neutron and Ceilometer and nobody seems in a
hurry to merge that functionality there... which is why I assumed the
