Abstract: A non-transitory computer-readable storage medium storing a program therein for causing a computer to execute a process that includes extracting, when a virtual computer running on one of physical computers is booted, time correction information corresponding to an attribute of a boot target virtual computer from time correction registration information which include the time correction information corresponding to the attribute of the virtual computer; and transmitting a boot command for booting the boot target virtual computer, based on the extracted time correction information, to the one of physical computers.

Abstract: A server facility includes a hardware resource group including at least a plurality of servers and a plurality of storage units; and a management server configured to store a user template file that contains information on a virtual system including a plurality of virtual machines, in a storage area, and facilitate the virtual system by assigning hardware in the hardware resource group to the user template file. The hardware resource group includes a plurality of hardware blocks each including a predetermined number of servers and storage units. In response to a virtual system copying request to copy a copying target virtual system of a first user to a second hardware block of a second user, the management server determines whether the second hardware block is able to provide a virtual machine in the copying target virtual system of the first user.
