Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to cloud computing. In particular, the present invention relates to methods and systems for executing virtual machine images in cloud computing. [Prior Art] By relying on powerful computing power, cloud computing enables thousands of end users to effectively use and connect via the Internet without worrying about the computing technology and access methods used. __ from the ^ computing power. In the cloud computing, the service is provided by the service. Virtualization technology is a technology widely used in cloud computing towels. In-the existing cloud computing shelf: The virtual machine is usually used to provide services to users. In the cloud computing, the virtual machine needs to execute the virtual machine image file, and the virtual machine image (4) usually includes the operating system, the installed application and the available disk space. Usually, a small virtual machine image file is 4 cents. The virtual machine image file can be hundreds of GB. For example, the TPM image file is about 100 GB. ^ In the first reading, in order to execute - virtual machine, it is necessary to copy the entire (including the operating system, the installed application disk space) from a storage device to a host, and connect to the image: The standard starts the virtual machine. When the virtual machine is started, 'the program is executed on the 4 virtual machine. If the virtual machine is affected!: The data is changed during execution', then the virtual machine stops (4) and the virtual file (4) is saved back to the storage service state. I507I2.doc 201214282 and the 0 m cluster will execute many hosts (that is, the t server in the tape end), and each host can execute many virtual machines. As mentioned in I 2 'for execution - virtual machine The image of the entire virtual machine needs to be copied from the storage device to the host. Because a relatively small virtual machine image is slaughtered, is- >1 D 7- ^ is the same, force 4 Qiu to 5 Xian, so the copy of the virtual machine image file will consume large | silver J & ^ consumption, full bandwidth. ..., after the virtual machine also needs to save the entire changed virtual machine video broadcast back to The storage server stores a large amount of network. [Summary] Therefore, there is a need for a method and system for performing virtual machine image improvement in cloud computing in the prior art. One aspect of invention Providing a virtual machine sound for performing a virtual machine in a host: a method of receiving a virtual machine image supply, and a virtual machine sound associated with the virtual machine image supply request = one request to send To - store the feeding device; receive the virtual machine (4) image: part, the portion of the virtual machine image includes at least the operating system core ~, the partition information and the building index information; by executing the virtual machine image" Receiving a virtual machine in the host; intercepting a file operation request executed by the program in the virtual machine; and transmitting a request for copying the slot associated with the file operation request to the storage server Receiving the file associated with the file operation request. According to another aspect of the present invention, a method for executing a virtual machine image in a host includes: receiving a virtual machine image associated with a virtual machine@image supply request sent by the host - please 150712.doc 201214282 == One part of the machine image is sent to the host. The virtual machine _ "w knife contains at least the operating system core, partition information and files..., the information '· receives the copy and broadcast sent by the host The file operation related to the file---Books. According to the present invention, the file related to the nuclear operation request is sent to the host. According to the present invention, the other party can perform the virtual machine shadow. #糸# The image includes: an image carrier for: receiving a virtual machine image supply request; requesting a storage server to copy a virtual machine image related to the virtual machine image supply request; receiving the virtual machine The image-partial portion of the virtual machine image includes at least an operating system core, partition information, and file index information; and the virtual machine is launched in the host by executing the received portion of the virtual machine image; a program loader for: intercepting a program operation request executed in the virtual machine; requesting the storage server to copy a file related to the broadcast operation request; and receiving a request related to the file operation request The file. According to another aspect of the present invention, a system for executing a virtual machine image in a host is provided, which includes: an image accessor for: receiving a copy and a virtual machine image transmitted by the host Supplying a request for one of the virtual machine images related to the request; sending a portion of the virtual machine image to the host of the virtual machine, the portion of the virtual machine image including at least the operating system core, the partition information, and the file index information; receiving by the host The transmitted copy requests one of the files associated with the file operation request; the Tan file associated with the file operation request is sent to the host. 150712.doc Λ 201214282 By the present invention, since only one of the virtual machine images is initially transmitted, the occupancy of the network bandwidth is significantly reduced. At the same time, since in the present invention, the application is driven to copy the file, only the necessary files will be copied from the remote storage server, thereby greatly reducing the occupation of the network bandwidth. The invention may be better understood by reference to the following description of the drawings, wherein the same or similar reference numerals represent the same or similar components throughout the drawings. The drawings, which are included in the description, are intended to be illustrative of the preferred embodiments of the invention Illustrative embodiments of the invention are described below in conjunction with the drawings. For the sake of clarity and conciseness (4), all features of the actual implementation are not described in this specification. However, it will be appreciated that in the development of any such actual embodiment, numerous specific implementation decisions should be made to achieve a developer's specific goals, such as compliance with system-related and quotient-related constraints, which may vary between different realities. . In addition, it will be understood that although this development effort may be complex and time consuming, it is a routine practice for those of ordinary skill in the art having the benefit of the present invention. Here, it should be noted that in order to avoid obscuring the present invention by unnecessary details, the component structure and processing procedure steps closely related to the solution of the present invention are explained only in the formula (4), and almost the present invention Irrelevant 々々, 1 I, · ', L is broken and omitted. During the work, the inventors of the present invention found that, in many cases, executing an application 150712.doc 201214282 requires only a virtual building to recover a portion of the file in the image, for example, according to the % method, while executing Apache. Only about (10) MB of files are required. However, in order to execute Αρ_, the entire virtual machine image of about 4 GB to 5 GB must be copied to the _host via the network, thereby causing a large amount of network bandwidth waste. Using the method of the present invention, copying only about 1 〇〇 Mr MB file required to execute Apache via the network, thereby greatly reducing the bandwidth consumption of the network. The inventors of the present invention have invented the present invention based on the above. Referring to Fig. 1, there is shown a system (4) G for performing virtual machine imagery in a host in accordance with an embodiment of the present invention. The system i (10) for executing virtual machine images in accordance with an embodiment of the present invention includes an image access device 1, a video loader 104, an application loader, and an image synchronizer 108. Or the system 100 for executing a virtual machine image includes two subsystems, wherein the image accessor 102 located in the word server constitutes a word server subsystem, and is located in the host and located in the virtual machine executed in the host. The image carrier (10), the application loader 106 and the image synchronizer i08 in the machine form a host subsystem. The image accessor 102 constituting the (four) ϋ subsystem is located at the storage server:. And includes an image converter, an image indexer and - image file access:. In this paper, the shirt image converter is used to convert an original virtual machine image into a part of the virtual machine Ilf image. The portion of the virtual (four) image includes at least the operating system core, partition information, and file index information. The image cable I Is used to generate a target for locating a rights in the virtual machine image, and the image converter first takes the operation system heart and points by analyzing the virtual machine image 150712.doc 201214282 Dragon Information, in turn, combines a portion of the virtual machine image with the file indexing information generated by the image index. The process of obtaining the system core and partition information tfl, the production line index information, and generating a portion of the virtual machine image can be implemented by any means in the art, and will not be described for the sake of brevity. The above processing procedures of image conversion and image* can be performed offline and the above processing programs of image converter and image indexer can be dynamically implemented. Fortunately, you can prepare this part of the virtual machine image offline in advance. The image converter can also embed an application loader into the virtual machine image to communicate with the application knower loader 106 located in the virtual machine executing in the host. The image file accessor is configured to receive a file read request from an application loader 106 located in a virtual machine executing in the host, read the file in the virtual machine image, and send it back in response To the application loader 1〇6, the image file accessor is also configured to receive the update file sent by the image synchronizer 108 located in the host, and update a virtual machine image stored in the server. The image carrier iG4' application ^HH6 and image sync (4) 8 constituting the host subsystem will be described below. The image carrier located in the host computer (1) is converted by the image (ie, copied from the storage server) by the image: the portion of the virtual machine image produced. After the part of the virtual machine image is loaded, the image manipulator 1G4 makes the virtual machine image X卩 tool appear based on the information of the dragon and the file index in the virtual machine image, and the present is present. The handler is similar to the handler executed by HyperManager I50712.doc 201214282 and will not be described for the sake of brevity. The application loader 1〇6 located in the virtual machine executing in a host includes a slot filer (file h00k) and an end image accessor (Id mage vistor). In this paper, the file interception program is used to intercept a (four) operation request of a program executed in a virtual machine (executed in the host) and send it to the local image accessor. The local image accessor receives the file operation request intercepted by the file interception program, checks the segment information and the file index information in the customized portion of the virtual machine image, and determines that the file operation request is related to the file operation request. Whether the file is located in the local data in the virtual machine executed in the host. If the file associated with the claim operation request is located in the local data, the corresponding file is read via the application interface of the application. If the file associated with the file operation request is not located in the local data in the virtual machine executed in the host, the file read request is sent to the image file access located in the storage server (4) image accessor 102. n 'The response returned by the image file accessor containing the file associated with the file operation is received, and the file related to the operation of the slot returned in the response is sent through the broadcast operation interface It is stored in the local data. The local image accessor is also used to incrementally (i.e., index increment) record the file index information changes made by the file operation. The image synchronizer 108 located in a host computer is configured to read the file index information change recorded by the local image accessor, and read the updated information in the local data by using the changed file information. The file 'sends the updated file to the shirt image stored in the image accessor 102 of the food server; the file accessor updates the I507I2.doc 201214282 virtual machine image in the storage server. The file interception program and the processing program of the local image accessor in the application loader 1-6 in the virtual machine executed in a host will be described in detail below. The file hook can be implemented by any means in the art and will not be described for the sake of brevity. When the application loader 106 receives a file insertion request for a program executed in a host, the master is used. The slot interception program in the bucket and cutter 1G6 intercepts the file operation request. For different standard operation requests, the == program cooperates with the local image accessor to respectively perform the corresponding correspondence, if the file operation request is a case open request (that is, the == obtain file information), then the target The interception procedure intercepts the heart two": Take t to develop it to the local image accessor. The local image visit = ::: district information and slot index information, and the Tan file index information is 彳S case Assignment table. Continued too 0 p clothing. Xuanben video accessor reads the file descriptor in the file information, index path, broadcast access rights, etc. == such as the corresponding file name, broadcast case storage 4 Resource, and the file open operation ends. The library file operation request is - file read request, then the project is intercepted 2 (four) (four) read request and sent to the local material access write. The W image access In the local index, search for the corresponding file information of the slot related to the file read request; if the request is related to the slot case, that is, (4) 5 Bay, the γ γ & 栳, 'heart though Case Bellow does not exist in the local cable... into the accessor via the - building case interception The sequence of the slot a is not sent to the image storage device (10) located in the server in March; 150712.doc 201214282 file accessor. The received file returned by the image file accessor contains the file and the file is read. After requesting a response of the related file, the corresponding file information of the slot related to the file reading request is recorded in the local index, and the file related to the file reading request returned in the Xuan response is via The application operation interface API is stored in the local data. If the local image accessor is in the book (4); 丨 + search and (4) the corresponding file information related to the request, the judgment is not the first - Reading the file related to the broadcast request, that is, the corresponding image information is already in the local index, and the local image accessor is based on the corresponding file information stored in the local index. The file operation application interface API directly reads the relevant project from the local data. ^ The (4) operation request is - file creation request, then the file is intercepted. 4 files are created and sent to The local image accessor first reads the segment information and the file index information, and the file name created by the file creation request is duplicated with the existing right name. The slot case (four) information _ For the case of the planting case, if there is no duplicate accessor through the blockade of the interception of the order year §/, then the 3 liters of the local image of the film is recorded in the local "the case established in the middle of the ^ and (4) The (4) operating application and the API establish a new file with the name to be established in the material.
