[0246] A description is given below of a second embodiment of the present invention.
[0247] The present invention is applicable not only to virtual machine operation servers but also to VTN (Virtual Tenant Network).
[0248] The VTN is a virtual network established on a controller in OpenFlow, such as OFC (OpenFlow Controller), in units of tenants.
[0249] Details of the open flow are described in Non-Patent Document 1.
[0250] User traffic transmission can be realized on the physical network by mapping the VTN established on the controller to the physical network.

The present invention provides migrating a virtual machine upon a virtual machine operation server at the nearest location as derived from location coordinate information of a client terminal, and connecting same to a virtual machine operation server with low wiring latency. Specifically, a location optimization server on a network administers a virtual machine operation server whereon a virtual machine which provides a service to a client terminal operates, and directs the migration of the virtual machine to a virtual machine operation server which is a migration destination according to the location coordinate information relating to the client terminal. In such a circumstance, the location optimization server carries out the direction relating to the migration of the virtual machine on both the migration source (present) virtual machine operation server whereon the virtual machine is operating and the migration destination virtual machine operation server.
Description
technical field [0001] The present invention relates to a virtual machine management system, more specifically to a virtual machine management system in a thin client system. Background technique [0002] Recently, systems called "thin clients" in which computers (clients) used by employees and the like have only the minimum necessary functions, and the server performs unified management of resources such as application software and files. In the thin client system, computers (clients) used by employees and the like are called "thin client terminals". [0003] In a screen forwarding type thin client system, which is a class of conventional thin client systems, a server implements a desktop environment (such as an operating system, application software, and files) using a virtual machine (VM) to provide a desktop environment for many thin client terminals . Thus, the provided desktop environment is a virtual desktop environment. Each thin client terminal can use the deskt...
