Abstract
A memory-use-information memory area stores therein a program ID, a request-source memory address, a request memory size which configure information for uniquely identifying a program file loaded into a storage area for virtual machine-A or storage area for virtual machine-B in association with a physical memory address. A memory reservation section uses, as the retrieval key, the program ID, request-source memory address, and request memory size of a program file corresponding to a memory reservation request to retrieval the memory-use-information memory area. When a entry that matches said retrieval key exists, the memory reservation section allows sharing of the memory area between a plurality of virtual machines.
