Description

  The present invention relates to a virtual machine communication setting technique.

  The virtual machine (Virtual Machine) running on the physical machine in the information processing system is assigned communication setting information (including MAC (Media Access Control) address, for example) based on the license agreement, and the virtual machine uses the setting information. By doing so, communication can be performed.

  When the setting information stored in the storage device of the physical server is lost due to a failure or the like, a problem may occur in the communication of the virtual machine. Therefore, it is preferable that the cloud system has a mechanism for restoring the lost setting information. However, there is no document that focuses on restoring the communication setting information used by the virtual machine.

FIG. 13 is a diagram illustrating a processing flow of processing executed when the information processing apparatus is activated. FIG. 14 is a diagram illustrating a processing flow of processing executed when setting information is received from the administrator terminal.

  First, consider a system as shown in FIG. In FIG. 1, an information processing apparatus having an EEPROM (Electrically Erasable Programmable Read Only Memory) and an HDD (Hard Disk Drive) can communicate with a network apparatus via a dedicated line or the like.

  In the information processing apparatus, three virtual machines (hereinafter referred to as VMs) are executed. Each VM has a hypervisor or the like based on setting information stored in the EEPROM via a user interface or the like (in this embodiment, data indicating a correspondence between a number for identifying a VM and a MAC address). Communication settings are made (for example, a network interface is generated). Here, the MAC address “B” is assigned to the VM with the number 1 based on the license agreement, the MAC address “C” is assigned to the VM with the number 2 based on the license agreement, and the number 3 Is assigned a MAC address “A” based on the license agreement. The data of each VM (for example, OS (Operating System) data and application programs) are stored in the HDD.

  The reason why the setting information is stored in the EEPROM, which is a storage device different from the HDD, is to prevent the setting information from being lost if the HDD fails. The reason why the setting information is not lost is to prevent the correspondence between the VM number and the MAC address from being changed by manually inputting the setting information after the loss (that is, due to a human error). It is.

  A MAC address corresponding to the MAC address of each VM is fixedly set in the network device. Therefore, even if the correspondence between the VM number stored in the HDD and the MAC address is changed, the setting on the network device side is not automatically changed, so there is a communication problem between the VM and the network device ( For example, a state in which communication cannot be performed or a packet is misdistributed) occurs. In such a case, the network device side must be manually set again.

  Here, as shown in FIG. 2, it is assumed that the setting information stored in the EEPROM is lost due to a failure. In such a case, there is no immediate effect on the operating VM, but when the information processing apparatus is newly started after the disappearance of the setting information, the setting information is not stored in the EEPROM. Communication settings based on the setting information are not performed. Therefore, the VM cannot be activated to perform communication.

  In such a case, as shown in FIG. 3, if the administrator can write the setting information corresponding to the setting on the network device side to the EEPROM via the user interface, the VM is written to the EEPROM. Communication settings are made based on the setting information. As a result, the VM and the network device can communicate normally.

  On the other hand, as shown in FIG. 4, when the administrator writes the setting information that does not correspond to the setting on the network device side to the EEPROM via the user interface, the VM correctly writes the setting information to the EEPROM. Communication settings are made based on no setting information. In the example of FIG. 4, the MAC address “A” is assigned to the VM with the number 1, the MAC address “B” is assigned to the VM with the number 2, and the VM with the number 3 is assigned. MAC address “C” is assigned. Therefore, a problem occurs in communication between the VM and the network device.

[Outline of this embodiment]
Therefore, in the present embodiment, as shown in FIG. 5, an area for saving the setting information is provided in the HDD of the information processing apparatus, and the setting information stored in the EEPROM is automatically saved. The setting information is saved when new setting information is written in the EEPROM. Also, if the setting information is not stored in the save area when the information processing apparatus is activated, the new setting information is stored in the EEPROM by storing the setting information stored in the EEPROM in the save area. It is also possible to cope with the case where the setting information is lost from the EEPROM before it is written.

  As shown in FIG. 6, for example, if the setting information in the EEPROM is lost, the VM cannot start and communicate, but the setting information written in the save area remains without being lost. Become. In such a case, the information processing apparatus is restarted after replacing the EEPROM.

  When the information processing apparatus is activated after the EEPROM is replaced, the activation corresponds to the first activation for the EEPROM. In such a case, as shown in FIG. 7, the setting information stored in the save area is restored to the EEPROM. As a result, the communication setting is performed for the VM using the setting information corresponding to the setting on the network device side, so that no communication problem occurs.

[Specific contents of this embodiment]
FIG. 8 shows an overview of the system in the present embodiment. The information processing apparatus 1 that executes the main processing of the present embodiment is connected to the administrator terminal 3 through, for example, a LAN (Local Area Network), and is connected to the network apparatus 5 through, for example, a dedicated line. . The administrator terminal 3 is operated by a system administrator. The network device 5 is, for example, a physical server, a network switch, or a storage device.

  FIG. 9 shows a hardware configuration diagram of the information processing apparatus 1. The information processing apparatus 1 includes a main body device 15 and an HDD 16. The main unit 15 includes a CPU (Central Processing Unit) 151, a RAM (Random Access Memory) 152, an EEPROM 153, a NIC (Network Interface Card) 155, and a bus 156. The CPU 151, RAM 152, EEPROM 153, and NIC 155 are connected by a bus 156. The main device 15 can access the HDD 16. The main unit 15 may have other hardware (for example, HDD).

  The main device 15 can be detached from the information processing device 1. In the present embodiment, for example, when a failure occurs in the EEPROM 153, the main device 15 is removed from the information processing device 1 and replaced with a new main device 15.

  FIG. 10 shows a functional block diagram of the information processing apparatus 1. The information processing apparatus 1 includes VMs 121 to 124, a virtualization processing unit 110 that is a hypervisor, for example, and a management unit 100. The virtualization processing unit 110 is realized by, for example, loading a program into the RAM 152 and executing it by the CPU 151. The VMs 121 to 124 are realized by the virtualization processing unit 110. The hardware (for example, the CPU 151, the RAM 152, and the NIC 155) of the main body device 15 is allocated to the VMs 121 to VM 124, but the data of the VM 121 to VM 124 is stored in the HDD 16. For the VMs 121 to 124, communication setting is performed by the virtualization processing unit 110 based on the setting information stored in the EEPROM 153. The management unit 100 is realized by loading a program (for example, firmware) into the RAM 152 and executing it by the CPU 151.

  FIG. 11 shows a functional block diagram of the management unit 100. The management unit 100 includes a first save unit 101, a second save unit 102, a restoration unit 103, a reception unit 104, a flag management unit 105, and an activation processing unit 106.

  The first save unit 101 executes a process of copying (that is, saving) the setting information stored in the EEPROM 153 to the save area of the HDD 16 when the information processing apparatus 1 is activated. The second saving unit 102 reads the setting information received from the administrator terminal 3 from the EEPROM 153 and executes a process of copying it to the saving area of the HDD 16. The restoration unit 103 copies the setting information stored in the save area of the HDD 16 to the EEPROM 153 when the information processing apparatus 1 is activated for the first time. When receiving the setting information from the administrator terminal 3, the receiving unit 104 stores the received setting information in the EEPROM 153. The flag management unit 105 manages an initial activation flag indicating whether or not the information processing apparatus 1 is activated for the first time. The activation processing unit 106 executes processing to be executed when the information processing apparatus 1 is activated.

  Next, processing executed in the information processing apparatus 1 will be described with reference to FIGS.

  First, processing executed when the information processing apparatus 1 is started will be described with reference to FIGS. 12 and 13. The activation processing unit 106 of the main device 15 executes processing at the time of activation of the information processing apparatus 1 (for example, initialization of a part of hardware) (FIG. 12: step S1). The process in step S1 is a well-known process and has no relation to the main part of the present embodiment, and thus detailed description thereof is omitted.

  The first save unit 101 determines whether the setting information is stored in the save area of the HDD 16 (step S3). It is assumed that the setting information on the HDD 16 that is actually set for the operating VM is deleted when the VM is stopped when the information processing apparatus 1 is shut down.

  When the setting information is stored in the save area of the HDD 16 (step S3: Yes route), the setting information stored in the EEPROM 153 may not be stored in the save area of the HDD 16. Therefore, the process proceeds to step S11.

  When the setting information is not stored in the save area of the HDD 16 (step S3: No route), the first save unit 101 determines whether the setting information is stored in the EEPROM 153 (step S5). If the setting information is not stored in the EEPROM 153 (step S5: No route), the saving cannot be executed, and the process proceeds to step S11.

  On the other hand, when the setting information is stored in the EEPROM 153 (step S5: Yes route), the first saving unit 101 reads the setting information from the EEPROM 153 (step S7).

  The first saving unit 101 writes the setting information read from the EEPROM 153 in step S7 to the saving area of the HDD 16 (step S9).

  The flag management unit 105 determines whether the initial activation flag provided in the storage device in the main device 15 is set (that is, the activation is the initial activation) (step S11). The initial activation flag may be provided in the EEPROM 153 or may be provided in another storage device of the main body device 15. The initial activation flag is set in a standing state at the time of manufacturing the main body device 15. Accordingly, if the information processing apparatus 1 is activated for the first time because the main body device 15 has been replaced, the initial activation flag is set.

  If the initial activation flag is not set (step S11: No route), the process proceeds to the process of FIG. On the other hand, if the initial activation flag is set (step S11: Yes route), the process proceeds to step S13 in FIG.

  Shifting to the description of FIG. 13, the restoration unit 103 determines whether the setting information is stored in the save area of the HDD 16 (FIG. 13: step S <b> 13). If the setting information is not stored in the save area of the HDD 16 (step S13: No route), restoration cannot be performed, and the process ends.

  On the other hand, when the setting information is stored in the save area of the HDD 16 (step S13: Yes route), the restoration unit 103 reads the setting information from the save area of the HDD 16 (step S15).

  The restoration unit 103 writes the setting information read from the save area of the HDD 16 in step S15 to the EEPROM 153 (step S17).

  The flag management unit 105 drops the initial activation flag provided in the storage device in the main body device 15 (that is, sets the information processing device 1 to a state indicating that the information processing device 1 is not activated for the first time) (step S19). Then, the process ends.

  As described above, when the information processing apparatus 1 is activated for the first time after the replacement of the main body device 15, the setting information stored in the save area of the HDD 16 that has not been replaced can be restored to the EEPROM 153. As a result, the VMs 121 to 124 can normally communicate after activation.

  In addition, since automatic evacuation is performed, human error is eliminated as compared with a case where setting information is manually input at the first activation.

  If the setting information is not stored in the save area of the HDD 16 when the information processing apparatus 1 is activated, the setting information stored in the EEPROM 153 is stored in the save area of the HDD 16 to create a new information. It is possible to cope with the case where the setting information is lost from the EEPROM 153 before the setting information is written to the EEPROM 153.

  Next, processing executed when setting information is received from the administrator terminal 3 will be described with reference to FIG.

  First, the receiving unit 104 of the information processing apparatus 1 receives setting information from the administrator terminal 3 (FIG. 14: step S21), and writes the received setting information in the EEPROM 153 (step S23). When the setting information is already stored in the EEPROM 153, the setting information already stored in the EEPROM 153 is updated with the received setting information. In addition, the reception unit 104 outputs the received setting information to the second save unit 102.

  The second saving unit 102 reads the setting information received in step S21 from the EEPROM 153 (step S25).

  The second saving unit 102 writes the setting information read in step S25 in the saving area of the HDD 16 (step S27). Then, the process ends.

  If the above processing is executed, the new setting information is written in the save area of the HDD 16 at the timing when the new setting information is written into the EEPROM 153. The possibility of disappearing can be reduced.

  Although one embodiment of the present invention has been described above, the present invention is not limited to this. For example, the functional block configuration of the information processing apparatus 1 described above may not match the actual program module configuration.

  Further, the configuration of each table described above is an example, and the configuration as described above is not necessarily required. Further, in the processing flow, the processing order can be changed if the processing result does not change. Further, it may be executed in parallel.

  In the above, other storage devices may be used instead of the EEPROM and the HDD. For example, not the EEPROM but another nonvolatile memory may be used. Further, instead of the HDD, another disk device (for example, SSD (Solid State Drive)) may be used. Further, the HDD that stores the VM data and the HDD having the save area may not be integrated.

  Further, the replacement target may not be the entire main device 15. For example, only the EEPROM 153 may be a replacement target. In this case, it is assumed that an initial activation flag is provided in the EEPROM 153 and the initial activation flag is set at the time when the EEPROM 153 is manufactured.

  The embodiment of the present invention described above is summarized as follows.

  The information processing apparatus according to the first aspect of the present embodiment includes (A) a first storage device, and (B) a determination unit that determines whether the activation is the first activation when the information processing apparatus is activated. (C) When the determination unit determines that the activation is the first time, the setting information stored in advance in the second storage device accessible by the information processing device and including the address is copied to the first storage device. A first duplicating unit; and (D) a setting unit configured to set communication of a virtual machine executed in the information processing device based on setting information stored in the first storage device.

  For example, when a failure occurs in the information processing apparatus, the next activation is the first activation, so that there is no setting information in the first storage device. Therefore, as described above, it is possible to prevent a problem from occurring in the communication of the virtual machine.

  In addition, when the (E) determination unit determines that the information processing apparatus is not activated for the first time, the information processing apparatus determines whether the setting information is stored in the second storage device, and the setting information is stored in the second storage device. In the case where the setting information is not stored, the information processing apparatus may further include a second copying unit that reads setting information from the first storage device and copies the setting information to the second storage device. Thereby, even if the setting information stored in the first storage device is lost, it can be restored.

  The information processing apparatus receives (F) setting information and stores the setting information in the first storage device, and (G) the setting information is input to the first storage device by the receiving unit. In this case, the information processing apparatus may further include a third duplicating unit that duplicates the setting information stored in the first storage device to the second storage device. Thereby, it becomes possible to cope with a change in the setting information.

  Further, the determination unit described above is (b1) based on data stored in the first storage device or another storage device in the information processing device for determining whether it is the first activation, It may be determined whether the activation is the first activation.

  Further, the first storage device may be a nonvolatile memory, and the second storage device may be a hard disk drive.

  In the communication setting method according to the second aspect of the present embodiment, (H) when the computer is activated, it is determined whether the activation is the first activation, and (I) the determination unit determines that the activation is the first activation. The setting information stored in the second storage device accessible by the computer and including the address is copied to the first storage device, and (J) based on the setting information stored in the first storage device. And a process for setting communication of the virtual machine executed in the computer.

  It is possible to create a program for causing a processor (for example, CPU) to perform the processing according to the above method, and the program can be read by a computer such as a flexible disk, a CD-ROM, a magneto-optical disk, a semiconductor memory, and a hard disk. Stored in a storage medium or storage device. The intermediate processing result is temporarily stored in a storage device such as a main memory.
