COMPUTER SYSTEM, CPU RESOURCE MANAGEMENT METHOD AND CPU RESOURCE MANAGEMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To implement a CPU resource management of programs to be executed on a virtual machine in a computer system running the virtual machine.SOLUTION: A computer system 100 includes: a host OS200; a VM control program 400 that causes a virtual machine to be operative; a guest OS500 that corresponds to the virtual machine; a user program 700 that is executed on the virtual machine; a VM resource management program 600 that passes first type CPU resource definition information for each virtual machine including allocation of a CPU resource to the user program; and a CPU resource management program 300 that receives the first type CPU resource definition information, re-allocates the first type CPU resource definition information to the user program within a range of the CPU resource allocated to the virtual machine, creates CPU resource re-definition information, and manages the CPU resource.SELECTED DRAWING: Figure 1
