摘要：A hypervisor sets all physical areas in an allocation area, which is allocated to avirtual machine from within a physical memory and is configured from a plurality ofphysical areas, to a write protect mode. In a case where a physical processor identifies
that the write-destination area from the virtual machine is in the write protect mode, thehypervisor manages the write-destination area as an updated area, and cancels the writeprotect mode of the write-destination area. At a certain point in time, the hypervisorcopies data inside the updated physical area from within the allocation area to a storagearea (a copy area) that differs from the allocation area. In a case where a prescribedfailure is detected in the physical area, the hypervisor restores data from the copy area.
