Description

  The present invention relates to a virtual machine activation control system, its activation control method, information processing apparatus, program, and recording medium, and in particular, a server that manages the operation of a virtual machine and other general servers operate on the same network. The present invention relates to a technique preferably applied to a system.

  Conventionally, Wake-on-LAN (WOL) is known as a technique for remotely operating a power supply operation (turning on) of a computer connected to a network such as a LAN. In WOL, a packet (magic packet) for starting a physical server can be broadcast in a network to which the physical server is connected to start the physical server. For example, when 100 computers are installed in a company, it has been conventionally necessary for a system administrator or the like to turn on the power one by one. However, in WOL, a magic packet is broadcast from the computer that issues a startup command to the network. By doing so, it is possible to start up a plurality of computers at a time.

  On the other hand, a virtual machine is known as a virtual computer realized using physical resources such as a CPU and a storage device of a computer. In a virtual machine, the virtual machine is generally stopped (especially hibernation or suspend) by software for managing the virtual machine. For this reason, the virtual machine does not directly return from the stopped state due to the WOL broadcast on the network. In order to remotely restore the virtual machine from the stopped state, a method in which the user remotely restores the virtual machine management software is common.

  As described above, the method for starting a physical server and the method for starting a virtual machine are different from each other, and each other's startup method cannot be applied directly. For example, the server that manages the operation of the virtual machine is the same as the other server. In a system operating on a LAN, the user must distinguish between activation targets and use different activation methods. From the viewpoint of usability, it is desirable to be able to start by remote operation in the same way without being conscious of the target to be started by the user.

  For example, Patent Literature 1 discloses a remote power supply control system that can simultaneously restore system power for a plurality of nodes in an architecture that is partitioned and organized by a plurality of nodes (physical servers). The system according to U.S. Patent No. 6,057,096 is partitioned into two or more static partitions, and remote power control for the partitions is achieved by a modified WOL implementation. The modified WOL modifies the magic packet filter for each network interface card (NIC) in the partition to be recognized by all nodes, or by the magic packet common to all nodes, the entire partition Remote restart across

Japanese Patent No. 3940410

  The system disclosed in Patent Document 1 assumes a case in which one node (corresponding to a virtual machine) is configured by a plurality of nodes, and by restarting each node in the partition in response to the same magic packet, A remote restart of the partition is realized. However, this activation control method cannot be applied to a case where a plurality of virtual machines are realized on one node. That is, when a plurality of virtual machines are realized on one node, the magic packet can only start the node as described above, and the virtual machine using WOL cannot be started.

  Therefore, the present invention provides a virtual machine using packets used for wake-on-run in a system in which a server that manages a virtual machine and other servers operate on the same network and a user starts a physical server using wake-on-run. The purpose is to be able to start the computer.

  An information processing apparatus according to one aspect of the present invention is a server apparatus that is used for wake-on-run, receives a network packet broadcast on a network, and provides a physical resource from a data storage apparatus that stores a virtual machine as an image file An execution request for the startup control of the virtual machine corresponding to the identification information included in the received network packet is made to the management apparatus that controls the startup of the virtual machine configured by reading the image file above.

  According to one aspect of the present invention, there is provided a virtual machine activation control method for a virtual machine configured by reading an image file on a server device that provides physical resources from a data storage device that stores the virtual computer as an image file. An activation control method, wherein the first device is used for wake-on-run and receives a network packet broadcast on the network, and the first device includes identification information included in the received network packet. The execution request step for making a virtual machine start control execution request corresponding to the second apparatus to the second apparatus, and the second apparatus starting control step for performing virtual machine start control according to the execution request.

  A virtual machine program according to an aspect of the present invention is a virtual machine startup control configured by reading an image file on a server device that provides physical resources from a data storage device that stores the virtual machine as an image file. A network packet received for a management process for receiving a network packet broadcasted on a network and used for wake-on-run to a computer and a management device for controlling the start of a virtual machine. And execution request processing for executing an execution request for starting control of the virtual machine corresponding to the identification information included in the virtual machine.

It becomes possible to start the computer.

The power supplies of the infrastructure server 230 and the virtual machine image storage device 210 are linked, and may be started and stopped at the same time to constitute one device (for example, a PC with a built-in HDD). In the second embodiment, the infrastructure server 230 and the virtual machine image storage device 210 are not always operating. In addition, the virtual machine management server 220 may be included in the infrastructure server 230 that operates the virtual machine to be managed by the virtual machine management server 220. In this case, the virtual machine management server 220 is configured by a virtual machine. The Of course, it is also possible to configure with a physical device.

When the infrastructure server 230 is not operating (step S204 / NO), the proxy activation device 240 issues and broadcasts a magic packet including the MAC address of the infrastructure server (step S205), and activates the infrastructure server 230. (Step S206). When the infrastructure server 230 is activated, the virtual machine image storage device 210 that is directly connected to the infrastructure server 230 and linked with the power source is also activated. Then, the proxy boot device 240 issues a virtual machine boot process execution request to the virtual machine management server 220 (step S207). On the other hand, the proxy activation device 240 discards the magic packet including the MAC address that does not match the registered MAC address (step S203 / NO).

  The virtual machine management server 220 performs a virtual machine boot process corresponding to the MAC address included in the magic packet in accordance with the execution request received from the proxy boot device 240 (step S208).

  As in the specific example of the first embodiment, the proxy activation server 1240 executes the proxy activation service as a service that operates on the OS. The software configuration of the proxy startup server 1240 is the same as that of the specific example of the first embodiment, but the proxy startup service uses the MAC address of the user virtual machine and the MAC address of the PC server 1220 that stores the user virtual machine. The data is stored in the memory or HDD in the table format shown in FIG. When the magic packet broadcast from the PC 1250 and received by the NIC is analyzed, the request is for the MAC address of the user virtual machine, and the PC server storing the user virtual machine is in the shutdown state, the PC A magic packet is transmitted from the NIC to the server to activate the PC server. Then, after the activation of the PC server is completed, the user virtual machine is activated by remotely accessing the PC server via SSH and remotely operating the management console of the virtual machine monitor of the PC server.

  The PC 1250 is the same as the specific example of the first embodiment. The operation of this example is omitted because the configuration corresponding to the configuration of the second embodiment described above operates similarly.

As shown in FIG. 16, the system as a specific example of the third embodiment is configured by connecting NAS 1310a and 1310b, a calculation server 1320, a proxy activation server 1340, and a PC 1350 to the same network. That is, one more NAS is added to the specific example of the first embodiment. Each device is configured as a real computer in the same manner as the specific example of the first embodiment. The correspondence with the third embodiment is the same as the specific example of the first embodiment.

  The proxy activation server 1340 executes a proxy activation service on the OS, and the software configuration is the same as that of the specific example of the first embodiment. However, the proxy activation service stores the MAC address of the user virtual machine and the MAC address of the NAS in which the user virtual machine is stored in the memory or HDD in the table format shown in FIG. In addition, when the magic palette received from the NIC that is broadcast from the PC 1350 is analyzed, the request is for the MAC address of the virtual machine, and the NAS storing the virtual machine is in the shutdown state, Then, the magic packet is transmitted from the NIC to activate the NAS, and after the activation of the NAS is completed, the calculation server 1320 is accessed remotely to activate the virtual machine.

  The NAS 1310a and 1310b, the calculation server 1320, and the PC 1350 are the same as the specific example of the first embodiment. The operation of this example is omitted because the configuration corresponding to the configuration of the third embodiment described above operates in the same manner.

[Fourth Embodiment]
FIG. 18 shows the configuration of a virtual machine activation control system according to the fourth embodiment of the present invention. The system according to the fourth embodiment includes a virtual machine image storage device 410, a virtual machine management server 420, an infrastructure server 430, a proxy boot device 440, a server boot device 450, and a router 460. The correspondence relationship with each device in FIG. 1 is the same as in the first embodiment. Hereinafter, a description will be given focusing on differences from the first embodiment.

  The difference from the first embodiment is that the proxy boot device 440 holds the MAC address of the virtual machine and the information of the physical resource used by the virtual machine as identification information 441 in association with each other. In addition to the information related to the virtual machine, the proxy boot device 440 holds information on the amount of free physical resources of an operating infrastructure server connected to the LAN. Further, an available physical resource amount may be stored for each operating infrastructure server architecture (CPU architecture or the like). In this case, the proxy boot device 440 also has an infrastructure server architecture on which the virtual machine can operate. You may make it memorize.

  As a method for the proxy activation device 440 to grasp the free physical resource amount, for example, the following can be cited. The proxy activation device 440 stores in advance an infrastructure server specification library that stores specifications (for example, CPU architecture, memory, and MAC address) of all infrastructure servers that can be activated. Since the proxy boot device 440 can grasp the operation status of the infrastructure server 430 from the network connection with the infrastructure server 430, it can obtain the physical resource amount of the operating infrastructure server and can be provided from the infrastructure server specification library. The total of the physical resources used by the virtual machines that have been started up is subtracted from the available physical resources. That is, the free resource amount for each architecture is obtained by the following formula.

  Further, in a system in which the infrastructure server 430 is always started by the proxy startup device 440, the fact that the proxy startup device 440 has started the infrastructure server 430 is used as a parameter as a method for grasping whether the infrastructure server 430 is operating. You may adopt the method of doing. Further, the proxy activation device 440 may collect the free resource amount by remotely operating the infrastructure server 430. As a more specific example, when Linux (registered trademark) is operating on the infrastructure server 430, the remaining memory capacity of the infrastructure server 430 is collected by reading "/ Proc / meminfo" of Linux (registered trademark). it can.

  In the fourth embodiment, the virtual machine image storage device 410 and the infrastructure server 430 are physical devices, but the infrastructure server 430 does not always operate as described above.

  FIG. 19 shows a flow of activation control of the virtual machine in the system of the fourth embodiment. First, the proxy boot device 440 registers the MAC address of the virtual machine to be booted and information on the resources used (step S401). In addition, the proxy activation device 440 collects and registers an available physical resource amount for the operating infrastructure server (step S402). Subsequently, the proxy activation device 440 registers the specifications of all infrastructure servers that can be activated (step S403). Thereafter, the server activation device 450 issues a magic packet including the MAC address and broadcasts it on the LAN 470 (step S404).

  The proxy activation device 440 receives and analyzes the magic packet flowing on the LAN 470, and determines whether the MAC address included in the magic packet matches the registered virtual machine MAC address (step S405). When the MAC address in the magic packet matches the registered virtual machine MAC address (step S405 / YES), the proxy activation device 440 obtains the used resource amount of the virtual machine corresponding to the registered MAC address, and the operating infrastructure The amount of free resources of the server is compared (step S406).

  When the free resource amount of the operating infrastructure server is larger and the physical resource amount is sufficient for using the virtual machine (step S406 / YES), the proxy boot device 440 activates the virtual machine to the virtual machine management server 420. A process execution request is issued (step S409). When the amount of resources used by the virtual machine is larger and the amount of available physical resources is insufficient (step S406 / NO), the proxy activation device 440 issues a magic packet including the MAC address of the stopped infrastructure server. Broadcast (step S407), and the infrastructure server 430 is activated (step S408). Then, the proxy boot device 440 issues a virtual machine boot process execution request to the virtual machine management server 420 (step S409). On the other hand, the proxy activation device 440 discards the magic packet including the MAC address that does not match the registered MAC address (step S405 / NO). In step 407, the infrastructure server 430 is selected according to the architecture of the virtual machine. The operation of selection will be apparent to those skilled in the art.

  In accordance with the execution request received from the proxy activation device 440, the virtual machine management server 420 performs a virtual machine activation process corresponding to the MAC address included in the magic packet (step S410). The virtual machine activation process by the virtual machine management server 420 is the same as that of the first embodiment.

<Specific Example of Fourth Embodiment>
As shown in FIG. 20, the system as a specific example of the fourth embodiment is configured by connecting a NAS 1410, a calculation server 1420, a proxy activation server 1440, and a PC 1450 to the same network. That is, two more calculation servers are added to the specific example of the first embodiment. Each device is configured as a real computer in the same manner as the specific example of the first embodiment. The correspondence with the fourth embodiment is the same as the specific example of the first embodiment.

  The proxy activation server 1440 executes a proxy activation service on the OS, and the software configuration is the same as the specific example of the first embodiment. However, the proxy activation service stores the MAC address, architecture, and physical resources (number of CPUs, memory capacity, etc.) of the user virtual machine in the memory or HDD in the table format shown in FIG. In addition, the available resource amount of the calculation server of the entire operating system is in the format shown in FIG. 22, and the specifications of the calculation servers (A), (B), and (C) are in the table format shown in FIG. Store in HDD. The proxy activation service analyzes the magic packet broadcast from the PC and received by the NIC, is a request for the MAC address of the user virtual machine, and the free resource amount is an architecture used by the requested user virtual machine If the necessary resources in the calculation server are not satisfied, a magic packet is newly transmitted from the NIC to the calculation server to start the calculation server. Then, after the activation of the calculation server is completed, the proxy activation service remotely accesses the management virtual machine of the calculation server and activates the user virtual machine.

  For example, it is assumed that the calculation server (A) 1420a is in the operating state, the calculation server (B) 1420b is in the shutdown state, and the free resource amounts of all the operating calculation servers are in the state shown in FIG. Here, when starting a virtual machine whose virtual MAC address is CC-11-22-33-44-55, the proxy start server 1440 can operate the virtual machine only with the calculation server (A) 1420a. If it is determined that the virtual machine can be operated by referring to the specification of the calculation server (B) 1420b having a CPU of the same architecture from the library and starting the calculation server (B) 1420b, The server (B) 1420b is activated. Thereafter, the virtual machine is started on the calculation server (B) 1420b.

  The configuration of the calculation server 1420 is the same as the configuration of the calculation server in the specific example of the first embodiment. However, while the calculation server (A) 1420a and the calculation server (B) 1420b are x86 processors, the calculation server (C) 1420c is a Power PC (registered trademark) processor. The NAS 1410 and the PC 1450 are the same as the specific example of the first embodiment. The operation of this example is omitted because the configuration corresponding to the configuration of the fourth embodiment described above operates similarly.

  According to the fourth embodiment described above, the activation proxy server stores the amount of physical resources required by the virtual machine and the amount of free physical resources that can be provided by the system, and sets the amount of used resources of the virtual machine to be activated. If the amount of free resources is insufficient, the infrastructure server is started to increase the amount of free physical resources. In addition to the effects of the first embodiment, the infrastructure server operates in response to the physical resource demand of the virtual machine. It is possible to increase or decrease the number. Furthermore, the proxy boot device stores the infrastructure server architecture for each virtual machine, so that even if the virtual computer can only operate on an infrastructure server of a specific architecture, the proxy boot device can store the infrastructure server on the virtual machine. And the virtual machine can be started up.

Thereafter, the server activation device 550 issues a magic packet including the MAC address and broadcasts it on the LAN 570 (step S502).

  The proxy activation device 540 receives and analyzes the magic packet that flows on the LAN 570, and determines whether the MAC address included in the magic packet matches the registered virtual machine MAC address (step S503). If the MAC address in the magic packet matches the registered virtual machine MAC address (step S503 / YES), the proxy activation device 540 identifies the virtual machine management server 520 that manages the virtual machine having the registered MAC address ( Step S504).

  When the virtual machine management server is operating (step S505 / YES), the proxy boot device 540 selects the PI library of the virtual machine management server (step S508), and the virtual machine management server performs virtual machine boot processing. Is issued (step S509). If the virtual machine management server is not operating (step S505 / NO), the proxy activation device 540 issues and broadcasts a magic packet including the MAC address of the virtual machine management server (step S506). The management server is activated (step S507). Then, the proxy boot device 540 issues a virtual machine boot process execution request to the virtual machine management server 520 (step S507). On the other hand, the proxy activation device 540 discards the magic packet including the MAC address that does not match the registered MAC address (step S503 / NO).

  The virtual machine management server 520 performs a virtual machine boot process corresponding to the MAC address included in the magic packet in accordance with the execution request received from the proxy boot device 540 (step S510). The virtual machine activation process by the virtual machine management server 520 is the same as in the first embodiment.
