PROBLEM TO BE SOLVED: To shorten time required for restoration of a virtual machine.SOLUTION: An information processing device comprises a plurality of processors, reading means, storing means, mapping means and restoration control means. The reading means reads information about a virtual address space used by a guest OS for each of areas obtained by dividing the virtual address space, when storing a state of a virtual machine on which the guest OS is operating. The storing means associates the information for each area read by the reading means with location information used for writing the information to an address space on memory at restoration of the virtual machine, and stores them in storage means. The mapping means maps the virtual address space which becomes a restoration destination of the information stored in the storage means on the address space on the basis of the location information stored in the storage means. The restoration control means separately assigns information for the areas stored in the storage means to each processor and causes the plurality of processors to parallelly perform processing to restore the information for the areas on the virtual address space. |
