Title: Virtual machine control program, virtual machine control system, and dump capturing method

Abstract: A virtual machine control system includes a dump target setting module that sets a flag that represents that a memory area is a dump target to each memory area that has been used by a guest OS, a dumping module that dumps to a file the memory area to which the dump target setting module sets the flag, and that removes the flag from the memory area about which dumping is completed, and a virtual machine control module that controls implementation of the guest OS, which operates on the virtual machine, and stops the implementation of the guest OS until the dumping module removes the flag from the memory area when the guest OS tries to access the memory area to which the dump target setting module sets the flag.
