We met with nova last week [1] and did there is some support for merging

So for the attach/detatch patch [2], there’s a nova cells + neutron job
[3] that’s being worked on in order to cover that functionality.  So
getting that test in place is the first step toward merging this one.

If you have experience with Devstack and/or gate testing, I’d encourage
you to help review that test so we can move forward.

Thanks!

Subject: [Openstack-operators] [Large Deployments Team] [nova] Cells v1
attach/detach blueprint

I reached out to nova today to see what is the best way forward on this
patch [1].  mriedem had created a blueprint skeleton for this already [2].

It sounds like it’s unlikely that nova would accept it, because it will
require a new CI job [3] and it goes against the philosophy of not
adding to the v1 code base.

They suggested we add it to the nova meeting agenda [4], by which I hope
to get to a definite “yea” or “nay” on if this can go forward.

It’s tomorrow (Thursday 11/5) 2100 UTC, #openstack-meeting.  Please
attend as you’re able.

Thanks,
Mike

I've got the cells + neutron test job config passing after some devstack updates and 5 new skips for network scenario tests that deal with floating IPs that cells appears to not be handling. I haven't yet dug into what the scenario test / floating IP issues are though, but I was going to propose those as adds to the rc file in the nova repo, then use that as a base dependency for a project-config change to add a job to the experimental queue.

It should be noted that cells v1 doesn't support the os-server-events API which is key for stability with nova + neutron in gate testing, so I think that would be a barrier to cells + neutron as a voting job in nova (eventually).
