An administration server comprises a storage unit which stores movement destination physical machine information which is capable of identifying a physical machine which is a candidate for moving a virtual machine which is being executed upon any of a plurality of physical machines. The administration server further comprises a control unit which executes the following controls. When shutting off power supply to a first physical machine group of a first control unit, the control unit executes the following. The control unit executes a detection which denotes that the information which is capable of identifying the physical machine which is the candidate for movement which is stored in the storage unit does not include a physical machine other than the physical machine which is associated with the first physical machine group. The control unit changes the movement destination physical machine information such that at least a physical machine which is associated with a second physical machine group is included in a candidate movement destination of a virtual machine.
