Zusammenfassung:PROBLEM TO BE SOLVED: To quickly complete the shift of a virtual machine operating in one physical server in a cloud system to another physical server.SOLUTION: A data processing system includes: a plurality of server devices in which a virtual machine operates; and a data relay device for transferring data to the server devices. The data relay device detects data for live migration among data to be transferred to the server devices. The data relay device detects the presence/absence of the convergence of the live migration in the virtual machine on the basis of the detected data for live migration. As for the virtual machine in which the non-convergence of the live migration has been detected, the data relay device holds data transfer to the virtual machine destination.
