In the cloudstack UI we do have certain parameters defined at Zone and Cluster level which can be used to override the global values. Say for zone level parameters browse to Infrastructure > Zones > <zone name > Settings tab. You will see bunch of settings defined. Similarly the case with cluster. I am sure there are lot more settings that be defined here. Also missing is settings at Storage for example. Or are you referring to defining a first class entity say Profile which can used to define a group of these settings and then the profile can either be assigned at the global level or zone or cluster or host level?
