Abstract: The virtual PC management system includes: a unit which acquires a power on/off state of a virtual machine from a computer via the network and stores it in a storage; a unit which acquires a power on/off state of a computer from the computer via the network and stores it into the storage; a unit which receives a start-of-use request for a virtual machine from the client machine and searches stored data of the storage unit for a computer which is in a power-on state and to which a virtual machine is not allocated, as an allocation candidate; a unit which allocates the virtual machine in accordance with the start-of-use request to the computer of the allocation candidate; and a unit which notifies, via the network, the computer of the allocation candidate of an instruction to turn on the power of the virtual machine.

Abstract: A master management system includes a duty master creating part that counts the number of users in each group of same-attribute users who desire to use each of the applications, that identifies the applications each of which the number of users desiring to use is equal to or larger than a predetermined number, that creates and stores a master in a master management database of a storage device; and an individual setting part that identifies virtualization-possible applications of the applications each of which the number of users desiring to use is equal to or smaller than the predetermined number, and that sets data on users desiring to use the virtualization-possible applications in the distribution destination list of a distributing server.
