<P>PROBLEM TO BE SOLVED: To efficiently and safely arrange and move a virtual machine by distributing the loads of an overall system. Ž<P>SOLUTION: The predetection of the resource shortage of a physical machine 120 and the layout and movement of a virtual machine 122 which is proper when it is viewed in the long and middle terms is achieved by recognizing and analyzing change in the load of a virtual machine 122 and the physical machine 120 by an approximate expression such as an equation of higher degree. In addition, the movement of the virtual machine 122 is scheduled in such a manner that the load is prevented from being deviated in the virtual machine 122, the physical machine 120 and the network by recognizing and analyzing the change in the load of the network by the approximate expression such as the equation of higher degree. In particular, a movement schedule is set so that the overlap of the peak of a CPU load in the physical machine 120 or the virtual machine 122 is avoided as much as possible.
