Zusammenfassung:	A computer system suited for migration of a virtual server between a plurality of physical servers that do not share a storage apparatus via a network is provided. The present invention is a computer system configured to: couple a plurality of computers together, in each of which a plurality of physical servers and a storage apparatus are directly connected within the same chassis, by directly connecting the storage apparatuses of the plurality of computers: and further have a management computer manage the plurality of computers. When the management computer selects another physical server other than a first physical server in a first computer among the plurality of computers as a migration destination of a virtual server, which operates in the first physical server in the first computer, it judges whether the other physical server exists in the first computer or exists in another computer different from the first computer among the plurality of computers.
