Description

  The present invention relates to a communication setting technology for virtual machines.

  Communication setting information (including a MAC (Media Access Control) address, for example) is assigned to a virtual machine (Virtual Machine) operating on a physical machine in the information processing system, 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 communication setting information used by a virtual machine.

FIG. 13 is a diagram showing a processing flow of processing executed when the information processing apparatus is activated. FIG. 14 is a diagram showing 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.

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

  Note that the setting information is stored in the EEPROM, which is a storage device different from the HDD, so that the setting information is not lost when the HDD fails. In addition, the setting information is not lost so that the correspondence between the VM number and the MAC address does not change due to the setting information being manually input after the loss (ie, due to a human error). 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 and the MAC address stored in the HDD is changed, the setting on the network device side is not automatically changed, which causes a communication problem between the VM and the network device ( For example, communication may be lost, or packets may be erroneously distributed. In such a case, it is necessary to manually redo the setting on the network device side.

  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, the VM in operation is not immediately affected, 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, so the VM is not stored. Communication settings based on the setting information are not made. Therefore, the VM cannot start and communicate.

  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 into the EEPROM through the user interface, the VM is written into the EEPROM. Communication setting is performed based on the setting information. As a result, the VM and the network device can normally communicate with each other.

  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 is correctly written to the EEPROM. Communication setting is performed based on the non-existing setting information. In the example of FIG. 4, the MAC address “A” is assigned to the VM having the number 1, the MAC address “B” is assigned to the VM having the number 2, and the VM having the number 3 is assigned to the VM having the number 3. MAC address “C” is assigned. Therefore, a problem occurs in communication between the VM and the network device.

[Outline of 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. Further, when the setting information is not stored in the save area when the information processing apparatus is started up, the setting information stored in the EEPROM is stored in the save area so that new setting information is stored in the EEPROM. Even if the setting information is lost from the EEPROM before being written, it can be dealt with.

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

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

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

  FIG. 9 shows a hardware configuration diagram of the information processing apparatus 1. The information processing device 1 has a main body device 15 and an HDD 16. The main body device 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 body device 15 can access the HDD 16. The main device 15 may have other hardware (for example, HDD).

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

  FIG. 10 shows a functional block diagram of the information processing device 1. The information processing device 1 includes VMs 121 to 124, a virtualization processing unit 110 that is, for example, a hypervisor, and a management unit 100. The virtualization processing unit 110 is realized by, for example, a program being loaded into the RAM 152 and being executed by the CPU 151. The VM 121 to the VM 124 are realized by the virtualization processing unit 110. The hardware of the main body device 15 (for example, the CPU 151, the RAM 152, and the NIC 155) is assigned to the VM 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, the virtualization processing unit 110 sets communication based on the setting information stored in the EEPROM 153. The management unit 100 is realized by a program (for example, firmware) being loaded into the RAM 152 and executed by the CPU 151.

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

  When the information processing device 1 is started up, 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. The second save unit 102 reads the setting information received from the administrator terminal 3 from the EEPROM 153, and copies the setting information to the save area of the HDD 16. The restoring 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 started 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 a first-time activation flag indicating whether or not the information processing device 1 is activated for the first time. The activation processing unit 106 executes processing that should be performed when the information processing apparatus 1 is activated.

  Next, processing executed in the information processing device 1 will be described with reference to FIGS. 12 to 14.

  First, the processing executed when the information processing apparatus 1 is started up will be described with reference to FIGS. 12 and 13. The activation processing unit 106 of the main body device 15 executes a process at the time of activation of the information processing device 1 (for example, initialization of some hardware) (FIG. 12: step S1). Since the process of step S1 is a well-known process and has no relation to the main part of the present embodiment, detailed description thereof will be 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 running VM is erased 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 does not have to be stored in the save area of the HDD 16. Therefore, the process proceeds to step S11.

  If the setting information is not stored in the saving area of the HDD 16 (step S3: No route), the first saving 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 save 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 save unit 101 writes the setting information read from the EEPROM 153 in step S7 into the save area of the HDD 16 (step S9).

  The flag management unit 105 determines whether or not the initial activation flag provided in the storage device in the main body 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 to a standing state at the time of manufacturing the main body device 15. Therefore, when the information processing apparatus 1 is activated for the first time because the main device 15 has been replaced, the initial activation flag is set.

  When the initial activation flag is not set (step S11: No route), the process shifts to the process of FIG. On the other hand, if the first activation flag is set (step S11: Yes route), the process proceeds to step S13 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 S13). 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 into the EEPROM 153 (step S17).

  The flag management unit 105 clears the initial activation flag provided in the storage device in the main body device 15 (that is, sets it 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 saved in the save area of the HDD 16 that has not been replaced can be restored to the EEPROM 153. As a result, the VM 121 to the VM 124 can normally perform communication after being activated.

  Further, since the evacuation is automatically performed, human error is eliminated as compared with the case where the setting information is manually input at the time of first activation.

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

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

  First, the reception unit 104 of the information processing device 1 receives the 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. Further, the reception unit 104 outputs the received setting information to the second saving 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 into the saving area of the HDD 16 (step S27). Then, the process ends.

  If the above-described processing is executed, the new setting information is also written in the saving area of the HDD 16 at the timing when the new setting information is written in the EEPROM 153. It becomes possible to reduce the possibility of disappearance.

  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 device 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 does not have to be as described above. Further, also in the processing flow, it is possible to change the order of processing if the processing result does not change. Further, it may be executed in parallel.

  Further, other storage device may be used instead of the EEPROM and the HDD. For example, other non-volatile memory may be used instead of the EEPROM. Further, instead of the HDD, another disk device (for example, SSD (Solid State Drive)) may be used. Further, the HDD storing the VM data and the HDD having the save area may not be integrated.

  Further, the replacement target does not have to be the entire main body device 15. For example, only the EEPROM 153 may be replaced. In this case, the initial start flag is provided in the EEPROM 153, and the initial start flag is set to the raised state when the EEPROM 153 is manufactured.

  The embodiments of the present invention described above can be 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, when the information processing apparatus is activated, whether the activation is a first activation. , (C) when the determination unit determines that the activation is the first time, the setting information, which is stored in advance in the second storage device accessible by the information processing device and includes the address, is copied to the first storage device. The information processing apparatus includes a first duplication unit and (D) a setting unit that sets the communication of the virtual machine executed in the information processing device based on the setting information stored in the first storage device.

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

  In addition, when the information processing apparatus (E) determines that it is not the first activation, 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. If not, it may further include a second duplication unit that reads the setting information from the first storage device and duplicates it in the second storage device. As a result, even if the setting information stored in the first storage device is lost, it can be restored.

  Further, the information processing apparatus receives (F) the setting information and stores the setting information in the first storage device, and (G) the receiving unit inputs the setting information to the first storage device. In this case, the setting information stored in the first storage device may be further included in the second storage device. As a result, it becomes possible to deal with a change in setting information.

  Further, the determination unit described above, based on (b1) data stored in the first storage device or another storage device in the information processing device for determining whether or not it is the first start, It may be determined whether the activation is the first activation.

  Further, the first storage device may be a non-volatile 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 having the first storage device is activated, it is determined whether the activation is the first activation , and (I) the activation is the first activation. If it is determined to be the start of, the setting information, which is stored in advance in the second storage device accessible by the computer and includes an address, is copied to the first storage device, and (J) is stored in the first storage device. It includes a process of setting communication of a virtual machine executed in a computer based on the stored setting information.

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