The use of reservations, limits, and shares offers the contextual ability for an administrator to allocate the compute resources of a host.
A reservation creates a guaranteed minimum resource allocation that the host must meet with physical compute resources to allow for a guest to power on and operate. This reservation is traditionally available for either central processing unit (CPU) or random access memory (RAM), or both, as needed.
A limit creates a maximum ceiling for a resource allocation. This ceiling may be fixed, or it may be expandable, allowing for the acquisition of more compute resources through a borrowing scheme...
