Description

Virtual computer providing system and providing method

The present invention relates to a virtual machine providing system and a providing method, and is particularly suitable for application to a virtual machine providing system and a providing method for providing a new virtual machine to a user by duplicating and initializing an existing virtual machine.

Conventionally, in order for a user to newly start using a computer, it is necessary to construct a computer environment. The construction of the computer environment is the construction of the computer so that it can be used. Specifically, the hardware and software suitable for the user's purpose are procured from the vendor, the procured hardware is installed, and the installed hardware is installed. For example, to set up software.

This construction of the computer environment requires a large time cost. In particular, in software development that requires operation tests for various combinations of hardware and software, it is necessary to repeat the construction of the computer environment many times. Therefore, as a result, much time is spent before the user can actually start using the computer.

Recently, in order to reduce this time cost, it has been proposed to use virtualization technology. In a virtual machine created using virtualization technology, its configuration information and data are packaged into one file. This packaged information is called a virtual machine image. By using this virtual machine image, it is possible to easily create a duplicate of the existing virtual machine.

∙ Virtual machine replication works on all hardware that has a hypervisor set up. The hypervisor is a control program for realizing a virtual computer, and is also called a virtualization monitor or a virtualization OS.

Therefore, by using virtualization technology, it is possible to reuse a computer environment (existing computer environment) that has been constructed once by the construction work of the computer environment to construct another new computer environment (new computer environment). Become. Therefore, the time cost required for the environment construction work can be reduced.

By the way, many users require a computer environment that combines various software. In such a case, even if a new computer environment is constructed from the existing computer environment using the conventional virtualization technology described above, if there is no virtual computer image that satisfies the user's request in the new computer environment, After all, you need to set up software that meets your needs. In this case, it takes a lot of time to provide a new computer environment.

Here, Patent Document 1 discloses a technique for creating a virtual machine that satisfies a user's request. Specifically, a virtual machine template having a minimum OS (Operating System) is prepared in advance, and a desired program selected by the user is set up for a virtual machine created by duplicating the virtual machine template. This is a technique for creating a virtual machine that satisfies the user's request. Note that the user selectable program is provided in the repository server.

US Patent Application Publication No. 20090300151

However, Patent Document 1 merely discloses preparing a virtual machine template having a minimum OS and setting up various programs provided by a repository server. Therefore, in the virtual computer creation method of Patent Document 1, after all, a setup work is required separately, and there is a problem that a lot of time is required until the virtual computer is provided to the user. In particular, the more programs that need to be set up, the more time it takes to provide a virtual machine.

Therefore, the present invention has been made in consideration of the above points, and is intended to provide a virtual computer providing system, a virtual computer providing method, and a program that can quickly provide a new virtual computer that satisfies a user's request. is there.

FIG. 10 is a conceptual diagram showing the flow of processing for providing a new virtual machine 20211A to the user by copying and initializing the virtual machine 20211 that is the copy source. Hereinafter, the replication source virtual computer will be described as “virtual computer 20211”, and the new virtual computer after replication will be described as “virtual computer 20211A” to distinguish between them.

First, in the virtual machine providing system 1A, when a request for a new virtual machine 20211A is received from the user B, the usage search unit 10211, the user name organization name search unit 10212, and the program name search unit 10213 satisfy the user B request. The original virtual machine 20211 is searched. Here, a case where the virtual machine 20211 currently used by the user A is obtained as a search result will be described.

Next, the retrieved virtual machine 20211 is duplicated by the virtual machine duplicating unit 10221 of the virtualization environment management program 1022.

Here, by providing the user B with the virtual machine 20211A immediately after duplication, the virtual machine 20211A including the OS (M1010) and programs (M1006, M1007) requested by the user B can be quickly provided.

However, since the virtual machine 20211A immediately after the duplication is simply a duplication of the virtual machine 20211 currently used by the user A, the user specific data M1003A of the user A, the organization specific data M1004A of the organization to which the user A belongs, The machine-specific data M1005A of the replication source virtual machine 20211 is also copied as it is. Therefore, the virtual machine 20211A immediately after copying cannot be provided to the user B as it is.

Therefore, it is necessary to initialize the computer environment of the virtual machine 20211A immediately after duplication by the duplicating virtual machine environment initialization unit 10231. In the initialization of the computer environment, the virtual machine data changing unit 102313 deletes the user specific data M1003A and changes the organization specific data M1004A and the machine specific data M1005A. Further, the program deletion unit 102312 deletes the program M1008A unnecessary for the user B. Further, the program adding unit 102311 adds a program M1009A that is necessary for the user B and that is not included in the copy source virtual machine 20211.

Through the above processing, by replicating and initializing the virtual machine 20211 being used by the user A, a new virtual machine 20211A according to the request of the user B can be provided to the user B.

A matching line is extracted from the use program management table 10303. Then, the connection virtual machine determination unit 102314 acquires the ID of the program stored in the program ID list field 103032 of the extracted row, and the initial ID associated with the acquired program ID and the copied new virtual machine 20211. Programs that are lacking in the new virtual machine 20211A among the use programs included in the existing virtual machine 20211 by comparing the IDs of the missing programs stored in the missing program list column 10265 of the computerized information list 1026 Is included (S2402).

If the connection virtual machine determination unit 102314 obtains a negative result in this determination, the connection virtual machine determination unit 102314 determines that a program lacking in the new virtual machine 20211A is not included in the use programs included in the existing virtual machine 20211. The process proceeds to step S2406.

On the other hand, when the connection virtual machine determination unit 102314 obtains a positive result in the determination in step S2402, among the use programs included in the existing virtual machine 20211, a program that is missing in the new virtual machine 20211A is included. It is determined that the program is a program to be used and is a deficient program (S2403).

Next, the connection virtual machine determination unit 102314 refers to the program management table 10301 (see FIG. 5), and the ID stored in the ID column 103011 matches the ID of the connection destination program set in step S2403. A row is extracted from the program management table 10301. Then, the connection virtual machine determination unit 102314 obtains the program name, version condition, and architecture information from the program name column 103012, the version column 103013, and the architecture column 103014 of the extracted row, respectively.

A row in which the version condition satisfies the acquired version condition and the architecture stored in the dependency architecture column 103085 matches the acquired architecture is extracted from the dependency management table 10308. Then, the connection virtual machine determination unit 102314 sets the ID program stored in the program ID column 103082 of the extracted row as the connection source program (S2404).

Next, the connection virtual machine determination unit 102314 instructs the connection setting change unit 10232 to execute connection processing. When the connection setting change unit 10232 receives the execution instruction from the connection virtual machine determination unit 102314, the connection setting change unit 10232 rewrites the connection source program setting included in the connection source virtual machine 20211A, so that the connection source program and the connection destination program are rewritten. A connection process for connecting to a connection destination program included in the virtual machine 20211 is executed (S2405).
