Patent number: 8443364Abstract: A user interface function for a virtual machine system based on a server or a PC is provided only by applying software without using SVP or the like. A control virtual machine is provided for controlling a virtual machine control screen which is displayed for defining virtual machines and instructing operations to the virtual machines. A virtual machine control program exclusively displays either a screen for each virtual machine or the virtual machine control screen in response to a screen switching instruction from an input device.Type: GrantFiled: March 29, 2010Date of Patent: May 14, 2013Assignee: Hitachi, Ltd.Inventors: Toyohisa Imada, Takashi Shimojo, Makiko Shinohara, Yoshihiro Harima

Patent number: 7461276Abstract: An adjustment method is able to effectively utilize a useless CPU power of a difference between a total CPU power required by a user and a CPU power of an installed computer. In a virtual machine system in which a plurality of virtual machines are operated on a physical machine, a total CPU power which results from totalizing CPU powers required by respective virtual machines is arbitrarily set within a CPU power of the physical machine, a CPU service rate is determined in such a manner that each virtual machine is operated within the thus set total CPU power and a CPU power of a difference between the CPU power of the physical machine and the total CPU power is assigned to a maintenance virtual machine.Type: GrantFiled: May 10, 2006Date of Patent: December 2, 2008Assignee: Hitachi, Ltd.Inventors: Toyohisa Imada, Takuichi Hoshina

Patent number: 4995037Abstract: A method and apparatus for providing data for adjusting an electronic computer having a main storage unit, in a system including a service processor connected to the electronic computer to maintain the same, and an external storage unit for storing data of internal registers of the electronic computer, which are read out by the service processor. An adjusting program is executed by the electronic computer until a logical failure is detected in the electronic computer to be adjusted. Once the logical failure is detected, execution is stopped at an instruction an arbitrary number of instruction before the instruction on which the failure was detected. Thereafter, the electronic computer is caused to re-execute the adjusting program. Data of internal registers and the main storage unit of the electronic computer is stored in the eternal storage unit through the service processor when the electronic computer stops execution of the adjusting program.Type: GrantFiled: May 11, 1988Date of Patent: February 19, 1991Assignee: Hitachi, Ltd.Inventors: Toyohisa Imada, Yoshiharu Kazama
