reduce the allowed instances on such a host. I would like to suggest, in addition to the current
proposition, make dynamic scaling configurable on a compute offering. When DS has been disabled
instances based on that service offering will get vCPUMAX=vCPU. The same goes for system offerings.
If this suggestion is not desirable I would like to suggest to only implement for system offerings.

Hey Joris - Appreciate your feedback and I think there is already and enhancement filed for
dynamic scaling controlled through compute offering - Check https://issues.apache.org/jira/browse/CLOUDSTACK-3941.
Since VCPUmax is configurable at cluster level, you can always set it to a lower value depending
on the load you are expecting in the cluster.
