Enabling and disabling memory oversubscription

Memory oversubscription (also known as memory ballooning) is a service daemon that handles dynamic memory allocation across virtual machines (VMs) running on a compute node.

This service allows VMs to release memory when it is no longer needed and, thus, ensures that at any given time no VMs have more memory allocated than is actually consumes. The benefit is more efficient use of available memory and improvements in workload performance. For more information, see Oversubscription in ThinkAgile CP.
