Resource Allocation

Starting with the Oracle VM Server for SPARC 2.0 release, the resource allocation mechanism uses resource allocation constraints to assign resources to a domain at bind time.

A resource allocation constraint is a hard requirement that the system must meet when you assign a resource to a domain. If the constraint cannot be met, both the resource allocation and the binding of the domain fail.
