Abstract
The management computer stores a configuration information of a storage, a configuration information of a host computer and a VM, an information on a service level of the VM, and a performance information of a storage subsystem and a network. If an access path that the host computer uses to access a volume is changed in response to a change of storage configuration, an I/O performance of the VM operating in the host computer may be changed. If the change of state of the storage is detected, the management computer calculates a change of state of whether a service level defined for the VM is satisfied, and selects an appropriate host computer in which the VM should be operated.
