A processor in a first information processing apparatus reads out data stored in a unit area of a memory used by a virtual machine and copies the data to a second information processing apparatus. The processor performs control for storing a modification history record in a buffer area allocated in association with the unit area, each time a modification is made to data in the unit area during a period after the copying. When the amount of modification history records in the buffer area exceeds a threshold, the processor recopies data stored in the unit area to the second information processing apparatus, in preparation for operation of the virtual machine on the second information processing apparatus. When the amount of modification history records does not exceed the threshold, the processor transmits the modification history records to the second information processing apparatus.

Information processing apparatus and migration method

An apparatus updates module information containing information on interfaces of modules contained in source code of a test-run target, when an update of an interface in the source code is detected. The apparatus refers to test-case information containing pieces of information on plural test cases, and selects a run-target test case from among the plural test cases, based on test run times taken in previous runs of the plural test cases. The apparatus generates a dummy module to include simplified code by simplifying code in source code of a second module to be statically linked to a first module called during a previous run of the selected run-target test case, so that the simplified code is not related to implementation of the interface indicated in the updated module information. The apparatus compiles the first module and the dummy module, and issues an instruction to run the selected run-target test case.

Test run control method and apparatus

A power consumption amount estimating apparatus for estimating a power consumption amount of a resource allocated to multiple virtual machines operating on a physical machine, the estimation being made for each virtual machine, includes a power consumption amount measuring unit configured to measure the power consumption amount of the resource; a time identifying unit configured to identify a start and an end time of a duration during which a processor is continuously allocated for one of the virtual machines; a power consumption amount obtaining unit configured to obtain the power consumption amount of the resource during the duration using the power consumption amounts at the start and end times; and a power consumption amount accumulating unit configured to accumulate multiple power consumption amounts of the resource for each virtual machine, the multiple power consumption amounts being obtained during multiple durations, respectively.

Power consumption amount estimating apparatus and power consumption amount estimating method

A non-transitory computer-readable recording medium has a program stored therein for causing a computer to execute a process. The process includes estimating a cost of executing a live migration of a virtual machine, using a count value of an access counter for counting the number of accesses to a memory allocated to the virtual machine, a capacity of the memory, and a bandwidth of data transfer between physical machines relating to the live migration.

Virtual machine management method and apparatus

A method for managing virtual machines, the method causing a management server having a database includes link relation information and connected to a plurality of physical servers, on which virtual machine hosts are installed, the method includes updating the link relation information in such a manner that a link between a virtual machine host and a first virtual machine guest is disconnected, when information regarding the first virtual machine guest cannot be acquired from the virtual machine host and updating the link relation information stored in such a manner that a link between a virtual machine host and a second virtual machine guest, when information regarding the second virtual machine guest is acquired from the virtual machine host.

Virtual-machine management program and method for managing virtual machines

A switch connects and disconnects an input and output control device to and from an input and output device. The switch includes a storage unit that stores therein a translation table for use in translating a physical address used on a virtual machine that a guest operating system specifies as a direct memory access transfer destination to the input and output device, into a physical address used on a real machine; and an address translating unit that translates an address contained in a direct memory access request issued by the input and output device into a physical address used on the real machine by referring to the translation table.

Switch, information processing apparatus, and address translation method

A controlling unit obtains server information from a server group in a chassis to store the obtained server information in a server information DB, an editing unit reads the server information from the server information DB, and generates, based on the read server information, as screen display information, physical server information, and logical server information including information on use application and attribute information for a logical server, which are related to a physical location of each physical server, and a displaying unit displays screen display information on a screen simulating the physical location of the physical server.

Server managing apparatus and server managing method

An optical wiring switching unit includes a first connection interface. A packet switch includes a second connection interface. A resource includes a third connection interface, and is formed with at least one of a server and a storage device. A control device controls the optical wiring switching unit to perform a switching of connection between the connection interfaces. The packet switch and the resource are connected to the optical wiring switching unit via the connection interfaces. A network is configured by connecting the packet switch and the resource with a control of the optical wiring switching unit.

Network configuring apparatus

A information retrieving method of realizing the improvement of retrieval performance without conducting fine-grain processing and allowing a parallelizing operation for sequential retrieval engines to be conducted easily. Accordingly, the information retrieving method according to this invention is made to connect retrieving servers in parallel with respect to a retrieval managing server through the use of a parallel framework which makes the retrieving servers conduct parallel processing by integrating the functions of the retrieving servers in a manner of directly using the functions thereof without changing. The data to be retrieved is distributed or substantially equally to the retrieving servers, while the retrieval requests from clients are successively broadcasted to the retrieving servers without waiting for the retrieval results from the retrieving servers. This invention can be effectively applied for fetching necessary information from a database retaining various kinds of information.
