VIRTUAL MACHINE SYSTEM AND CONTROL METHOD OF THE VIRTUAL MACHINE SYSTEM
First Claim
1. A control method of a virtual machine system including a plurality of physical machines, a system disk and a management part to control virtual machines and in which a plurality of logical virtual machines are operated by control parts in the physical machines, each of the virtual machines including a logical communication network interface and a logical storage connection interface and including as address information a virtual network address and a virtual storage interface address, the system disk in which a system to activate the virtual machine is stored being connected to the logical storage connection interface, whereinwhen the virtual machine operating in the physical machine is transferred to another physical machine, the management part performs the following:
- stopping the virtual machine of transfer source;
defining the virtual machine of transfer destination in the other physical machine;
changing configuration information of the virtual machine of transfer source and the virtual machine of transfer destination in state that the virtual machine is prevented from being activated; and
canceling prevention of activation of the virtual machine of transfer destination after the configuration information is changed.

Abstract
In a control method of a virtual machine system, when a virtual machine operating in a physical machine is transferred to another physical machine, a management server stops the virtual machine of transfer source and defines a virtual machine of transfer destination in the other physical machine. A virtual network address and a virtual storage interface address of the virtual machine of transfer source is exchanged with a virtual network address and a virtual storage interface address defined in the virtual machine of transfer destination in the state that the virtual machine is prevented from being activated and then prevention of activation of the virtual machine of transfer destination is canceled, so that transfer processing can be made safely by simple procedure.
