Host system and remote apparatus server for maintaining connectivity of virtual in spite of live migration of a virtual machine

The present invention even when moving the physical host via the live migration of virtual machines to a remote device connected to the virtual machine and the virtual held a virtual connection to the virtual machine and the remote device can be used virtual device that does not have a virtual machine user breaks It relates to systems and methods for. And a host system according to an embodiment of the present invention to do this is to perform a live migration to move the virtual machine, the virtual machine migration control unit, and a virtual connection to the remote device, the server device is connected is assigned to the virtual machine to drive the virtual machine from entering into, and provides the virtual connection receives the data to be sent and received from the device to completion from the time when the live migration from a remote device server, information for the conclusion of a virtual connection to the destination host for the live migration or start a live migration received from a host may comprise a virtual control to be provided, and provides the virtual machine the virtual machine drives the data received by the virtual connection after the service to control the migration controller that drives the live migration of virtual machines to the virtual connection have.
