Thank you a lot! :-).
Actually, we are also working in parallel to implement the algorithm with tacker, but for this project we will only use the basic modules in OpenStack and Heat.

If the scheduler hints are no longer supported, what is the correct way to give the scheduler personalized input with the instance details? 
Best regards Giuseppe

You can head over to Freenode IRC on the #openstack-neutron channel to chat about Neutron service function chaining. The #tacker channel has folks interested in NFV orchestration and should be able to help you out.
