Abstract
An apparatus controls migration of a virtual machine between plural servers in a communication network. The apparatus acquires flow information by classifying, for each of virtual machines, pieces of data transmitted and received in each of the plural servers into flows having respective different destinations. The apparatus selects, based on the flow information, a migration target which is a virtual machine to be migrated from a first server whose number of virtual machines in operation is relatively large to a second server whose number of virtual machines in operation is relatively small, from among virtual machines in operation in the first server, by giving a higher priority to a virtual machine whose matching number of flows is larger, where the matching number of flows indicates a number of flows that are currently processed by both the virtual machine and the second server.
