Background: SuperCluster LDoms are frequently deployed with exavm zones for database and application zones and zone clusters in the application (General Purpose) Domains. The present documentation seems to infer you can allocate all of the cores (vCPU) to the zones and they will be shared with the global zone. This however is not how it should be architected on SuperCluster products.

Goal

 Determine the minimum number of cores that should be retained for the global zone per LDom.
