Abstract
A virtual machine system capable of considerably improving its performance by preventing a variation of time slice values of logical processors and strictly ensuring the concurrent running of a plurality of logical processors belonging to the same virtual machine, in the configuration and management of virtual machines of a multi-processor structure having a plurality of logical processors. A method of controlling a virtual machine running time in the virtual machine system includes collectively storing time slice values of logical processors in a virtual machine to which the logical processors belong, and making a virtual machine control program for supervising and controlling the logical processors to store and manage the time slice values.
