PROBLEM TO BE SOLVED: To provide a system and method for allocating storage devices/logical units to virtual machines on demand and to allow a large number of virtual machines to execute on the same host computer. SOLUTION: Computerized information system and method having several virtual machines share common resources such as system storage resources. The system contains host computers 1A, 1B-1N executing several virtual machines, system resources organized into several resource groups, and a resource controller associating a resource group with a virtual machine executing on the host computer. When a state of the virtual machine changes, the resource controller releases the previously allocated resource group and when a request to execute another virtual machine is received, a new resource group is allocated to the host computer.
