>
> Currently in a CloudStack deployment, only one of these planners can be used 
> for all VM deployments. The global parameter 'vm.allocation.algorithm' 
> decides which planner will be used.
> However there could be a need to be able to choose different planning 
> strategies within a single CS deployment. So letting Admin choose a 
> deployment planner for a set of VMs will be helpful.
> To enable this, proposal is:
>    1)  Expose deployment planner as part of a ServiceOffering API. By 
> default, the value can be set to the default CS FirstFitPlanner, but admin 
> can override it and set some other strategy as per needs.
>    2) Add a resource reservation mechanism to let deployment planners co-exist
