In particular, a process for utilizing a virtual pool to manage the generation of virtual machines, and completing a virtual machine that provides customer service.

Because of the abundance of network bandwidth, the maturity of cloud computing technology and virtualization technology, it is possible to use the virtualization platform proposed by cloud service operators to put the application services and storage space to be used on the virtualization platform. Users only need to use a thin client computer to access remote resource pools through the network (cloud service operators provide storage devices, computing power and various applications in real hardware resources) to save resources. . The cloud service provider provides the equipment for loading and unloading. The user can apply for rent and lease at any time through the network. When the program needs more resources to execute, it can rent multiple virtual machines at once, when the workload is not as expected. More, instant rent-off, cost savings; users do not need to know the configuration and knowledge of hardware resources, the configuration of these hardware resources is managed by cloud service operators, so convenient and energy-saving, making more and more users use virtual The machine execution program completes the work to be performed on the local host.

However, for cloud service operators, the face is getting more and more Many users propose to rent a virtual machine service, how to effectively and quickly provide virtual machines to customers? How to ensure that the virtual machine that the customer is renting is quality?

In view of the above-mentioned cloud service provider's virtual machine supply and demand requirements, the inventor of the present invention finally succeeded in researching and developing this method of rapidly generating a virtual machine by using virtual pool management after continuous experiment and execution program improvement.

In view of the shortcomings derived from the above-mentioned conventional methods, the inventors of the present invention succeeded in research and development to complete the present invention after improving and innovating, and after painstaking research.

The main purpose of the present invention is to help a virtual machine supply subsystem in a cloud service provider operation obtain a virtual machine that can be used for installation, and can quickly provide services to customers. When the customer proposes a large number of virtual machine service requirements, it can also efficiently manage the virtual machine that can provide the service, and quickly provide the configured virtual machine to the customer for lease.

The secondary purpose of the present invention is to provide a quality virtual machine. When the system pursues a fast provisioning service, it usually lacks quality, and the copied virtual machine is provided to the customer. When the customer starts to use the virtual machine, the user must The self-completed rapid build service, the network configuration service, and the system update service are completed, and the virtual machine obtained by the customer has no quality at all. In order to provide high-quality services, virtual pool management can be used to enter virtual pools that can provide services, and then selected to provide system quality. Quality guaranteed virtual machine.

In order to achieve the above-mentioned main object of the invention, the present invention provides a virtual machine for quickly providing a supply system for a customer. To achieve the purpose of speeding up, in determining a replica template, the task loading is determined. The key to speeding up the replication of templates is to use a lower-loaded template for replication, reducing the risk of frequent I/O accesses; writing all operating system initialization data to the virtual machine on-off machine standardization process to update The structural configuration of the operating system reduces the time it takes to provide a complete virtual machine for the system.

In order to achieve the secondary purpose of the above invention, the three virtual pools have different production purposes through the management of the virtual pool, the reserve pool is for production purposes, the offline pool is for preliminary service purposes, and the online pool is as the name suggests, the virtual machine Through these three consecutive virtual pool steps, the provisioning system can obtain the serviceable virtual machine in the online pool, spend less time searching for the serviceable virtual machine, and can enter the online line because of the differentiation of the virtual machine behavior. The virtual machines in the pool are the products obtained after multiple verifications, and the quality is guaranteed.

The virtual machines that can be served in the online pool are all powered off, which can reduce the waste of resources in the virtual pool, and by this resource management, increase the resources that are being copied and the resources that can be used by the virtual machines in use.

In summary, the system provides less time to create new virtual machines and utilizes virtual pool management to get better quality virtual machine services.

The present invention is a process for fabricating and managing a virtual machine. FIG. 1 is a schematic diagram of a virtual pool management for generating a new virtual machine in a provisioning system by using a virtual pool management method for quickly generating a virtual machine. Figure 1 is a complete representation of the invention to illustrate the virtual pool as the primary method of virtual machine management and to perform different implementation actions.

As shown in FIG. 1, the system executor 101 includes a product resource management system for providing customer service services, a virtual machine template 102 of various operating systems supported in advance, and the following OS: Windows XP, Win7, Windows2008, Fedora, CentOS, Ubuntu; a new virtual machine storage 103, the newly generated virtual machine can be placed in the cluster, a preparation pool 104 of the virtual pool operation process module, an offline virtual pool operation process The offline pool 105 of the module, the online pool 106 of the online virtual pool operation process module.

The provisioning subsystem utilizes the system executor 101 that provides product resource management of the customer's provisioning service as the sender of the execution command, and also the recipient of the response. When receiving various reply messages in the process, the processing error message module 114 can be processed. Know what response the system performer 101 should do next. The virtual machine template 102 of the various operating systems supported in advance is used to find the operating system template required by the system executor 101 by using the minimum template load of the hash form, and enter the preliminary pool 104 of the preliminary virtual pool operation process to perform the copy virtual The action 107 of the machine, the action 108 of the standardized virtual machine, and the action 109 of the operating system update. These action functions are all The virtual machine function action library is provided.

After the above actions are completed, the offline pool 105 of the offline virtual pool is operated, and the virtual machine name is learned by the storage material device 113 to perform the action 110 of searching for the virtual machine and the action 111 of resetting the virtual machine name and storing it back to the storage device device 113. .

After the above actions are completed, the line pool 106 is accessed through the operation process of the online virtual pool, and the action 112 for providing the client demand supply service is completed by the system performer 101 according to the customer requirements.

The method of making and managing a virtual machine provides a new virtual machine to enter the online pool 106, completes the group construction of the operating system, that is, completes a new virtual machine generation process.

When the customer requests the application of the virtual machine, the system executor 101 will perform the action 112 of providing the client demand for the service in the online pool 106 in response to the customer's order. This is not a copy of the provisioning system process. Within the invention.

2 is a flow chart of a method for preparing a virtual pool in a virtual pool by using a virtual pool to quickly generate a virtual machine. As shown in Figure 2, after the virtual machine is controlled by this process, it can enter the virtual machine offline pool to wait.

The method selects a specific operating system to copy the gene, and transmits the name of the operating system to the system executor. The system executor searches for the specified template in the established virtual machine template group, and the template names in the template group are all The name of the operating system is included. If not found, the error message is returned to the system executor and then the program is left. Find the templates of the same operating system and get the workload of these templates, store them in the template hash form, and use the hash The definition of the form - can not exist in the keyword (Key) the same string, only different template names can exist in the hash form, if you find the template of the same string, the latter with a smaller load value will replace the larger The former of the load value has the advantage of reducing the number of templates in the hash form and increasing the speed of comparing the load values in the hash form.

For example: there are multiple templates named after Windows 2008 in the template group. When you find a template named after Windows 2008, compare it with the Key in the hash form. Is there any data named by windows2008? If there is any comparison The load of the two, if the new windows2008 template has a small load, it will replace the template load value in the original hash form, and so on, in the hash form will record the template name in the current template group The minimum load.

Then set the virtual machine's replication specifications, configuration configuration and storage data as the basis for replication; look for the template replication gene in the template hash form and compare the load to get the least load, and generate a new virtual machine password. , stored in the database along with the name of the new virtual machine to be set by the system executor, in case the query is changed in the offline pool.

In the function of the programming language - the function of multiple execution (Thread), in addition, the execution order of the copy is executed. The execution sequence of the original system performer uses the execution sequence sleep (Sleep) to wait for the state of the newly generated virtual machine to enter the offline pool. After the waiting time has passed the experiment, the minimum waiting time is obtained. If the new virtual machine successfully enters the offline pool, the process ends. In addition, the process of generating the copy is configured to be configured as Start, according to the template operating system, establish the Internet basic protocol and rapid system implementation specifications, and set the shutdown command belonging to the Microsoft operating system, start the template copy action, and write the new name to the newly generated virtual In the machine, the system will reply to the job result and judge whether the copy is successful. If it is not successful, it will respond to the system executor and leave the program.

If the copying is successful, the machine specification operation of the newly generated virtual machine is started. The operation of the specification of the operating system is completed in the process of copying at the beginning, and all required specifications are written and newly written. In the virtual machine, if the write specification is not successful, the error message is returned to the system executor and the program is left. If the writing is successful, the machine starts to power on the newly generated virtual machine. If the startup is unsuccessful, the error message is sent to the system executor and the program is left.

If the booting is successful, the newly created virtual machine starts to do the rapid system setup update according to the specification. The virtual machine system of different operating systems takes different time to build. When the quick system setup update is completed, the virtual machine is executed. The action, if unsuccessful, responds to the system executor with an error message and leaves the program. If the shutdown is successful, the newly generated virtual machine enters the offline pool, and the system executor program ends the process procedure because the newly generated virtual machine enters the offline pool.

FIG. 3 is a flowchart of an operation procedure in an offline virtual pool stage of a method for rapidly generating a virtual machine by using a virtual pool management according to the present invention. As shown in Figure 3, after the virtual machine is controlled by this process, it can enter the virtual machine to wait for the line pool to provide the system performer to make the service. Business.

When the newly generated virtual machine enters the offline virtual pool stage, the basic settings of the virtual machine are completed. The process of the offline pool process is to check the quality and process of the virtual machine, and the virtual machine check operation is confirmed again to ensure that the virtual machine can be provided. The integrity of the virtual machine.

Determine whether the reserve pool and offline pool exist. If it does not exist, respond to the executor with an error message and leave the program. This judgment is to ensure that the newly created virtual machine has entered the reserve pool and the offline pool. After the control of the two virtual pools, the system executor does not receive any error message to ensure the quality of the virtual machine. Then, it is judged whether the name of the virtual machine to be set is repeated. If it is repeated, the error message is returned to the system executor and the program is left. Then, it is determined whether the original template exists. This is to confirm whether there is an abnormality in the copy process. If it does not exist, an exception is generated, and the error message is sent to the system executor to leave the program.

After determining that everything is normal, use the known name stored in the database to search for the newly created virtual machine to determine whether the newly created virtual machine exists. If it does not exist, the error message is returned to the system executor and the program is left. The name of the newly created virtual machine is renamed by the name set by the system executor to determine whether the rename is successful. If it is unsuccessful, the error message is returned to the executor and the program is left. After that, the newly renamed virtual machine enters the online pool. When the new virtual machine enters the online pool, the method completes the virtual machine production.

Use the template to quickly copy the virtual machine and build the preparation pool of the fabric to determine the virtual machine that meets the requirements; then in the offline pool to search for the virtual machine and re-name the process, complete the ensured arrival The virtual machine of the line pool is a virtual machine that can be powered on.

In order to obtain an efficient virtual machine production process, the present invention has the following features in the program:

1. The present invention shortens the speed of copying virtual machines by selecting the operating system template with the least load and the minimum number of executions (Tasks). This selection method can concentrate resources to speed up the copying speed.

2. The present invention utilizes a plurality of Hash Map Tables to control the selection of templates and copying programs, which reduces the number of template requirements and increases the speed of comparing loads.

3.
