Comment 19 for bug 1709902

Newton is end of life upstream. I'm not sure how cleanly the backport would apply to Ocata, but if the bug exists in Ocata then I don't see why we wouldn't backport it there as well. The only major difference is in Ocata, the ResourceTracker in nova-compute should periodically (every minute by default) heal the allocations for the instances running on that host. That stopped in Pike once all your computes were upgraded because the scheduler (in Pike) creates the allocations, not the computes.
