The determination part determines whether there is a restoring process being performed for a virtual machine when trouble of the virtual machine or trouble of physical equipment operating the virtual machine is detected. The deletion part deletes correspondence between the virtual machine and a storage region used by the virtual machine or deletes the correspondence and a virtual machine instance of the virtual machine as a first restoring process when there is not the restoring process being performed. After the physical equipment operating the virtual machine is selected, and the correspondence is deleted or the correspondence and the virtual machine instance are deleted, the reconstitution part makes the selected physical equipment form the virtual machine again as a second restoring process.SELECTED DRAWING: Figure 1
