Hi Sylvain, The Smart Scheduler work should work along withGantt easily, as it is just another scheduler driver, instead of using the Filters, it will have a separate mechanism of solving the placement problem all at once. So just like how it currently works along with Nova scheduler, it should easily be integrated into Gantt, is what I would imagine. I have not looked very closely at the Gantt work, but I assume if you claim, no behavior changes in Gantt, and if you are continuing to use FilterScheduler, SmartScheduler should fit in too.
I will try to update the nova-spec ([1] https://review.openstack.org/#/c/96543/) for Smart Scheduler, and let the review continue sometime soon. Thanks, Yathi.
