PROBLEM TO BE SOLVED: To improve processing efficiency and data precision relating to profiling processing, and to achieve shortening of an operation period and cost reduction relating to the construction/management of a virtual machine system having a profiling function. SOLUTION: (1) At first, identification information of a virtual machine assigned to a CPU is transmitted to a profiling support mechanism 250 by a hypervisor 240. (2) The profiling support mechanism 250 sets the address of a profiling program to the performance monitoring interrupt vector of the CPU. (3) The CPU directly calls the profiling program on a virtual machine without using the hypervisor 240 by performance monitoring interruption. (4) The profiling program performs profiling processing, and (5) directly outputs a log to a log database 260 without using the hypervisor 240. COPYRIGHT: (C)2009,JPO&INPIT
