<p>The present invention speeds up stop processing for high priority virtual machines. A memory unit (1e) stores information indicating the priority of each virtual machine (1a, 1b, 1c, 1d). A controller (1f), when executing stop processing in parallel on the virtual machines (1a, 1b, 1c, 1d), references the memory unit (1e) and selects a virtual machine (1a) from among the virtual machines (1a, 1b, 1c, 1d). Also, the controller (1f) references the memory unit (1e) and selects virtual machines (1c, 1d) from among the virtual machines (1b, 1c, 1d) having a lower priority than the virtual machine (1a). The controller (1f) reduces the amount of resources allocated to the selected virtual machines (1c, 1d) and uses the resources corresponding to the reduced resource allocation to increase the amount of resources allocated to the virtual machine (1a).</p> |
