Abstract
A system for controlling virtual main memories (VMMs) of a plurality of virtual machines (VMs) which has a section for detecting an overload state of a VMM of any VM, a section for requesting a VMM corresponding to a required capacity in response to the detection. The system also includes a section for monitoring load states of the VMMs of other VMs in response to this request, a section for selecting an unbusy VM in accordance with the monitoring, a section for releasing the VMM corresponding to the requested capacity from the selected VM, and a section for supplying the released VMM to the VM requesting a VMM.
