PROBLEM TO BE SOLVED: To provide a virtual machine determination program for determining a virtual machine to be migrated when migrating a virtual machine on a physical machine to a virtual machine on another physical machine. SOLUTION: A computer is made to function as calculation means and as virtual machine determination means. The calculation means reads out, by the virtual machine determination program, the number of pages updated for each elapsed time from a table for controlling the number of pages, which in turn is a previous record with the number of pages updated for each virtual machine and each elapsed time, reads out transfer time for each page from a table for recording the transfer time, which in turn is a previous record with a transfer time for each page required for transferring pages from a physical machine on which the virtual machine is mounted to another physical machine, and calculates transfer time required for performing a page transfer of a predetermined virtual machine on a predetermined physical machine to another virtual machine on another physical machine from the number of pages and the transfer time read out, for each virtual machine. The virtual machine determination means determines the virtual machine of which calculated transfer time is the shortest as the one to be migrated. COPYRIGHT: (C)2009,JPO&INPIT
