[0029] The embodiments of the present invention provide a method, apparatus, device and storage medium for creating a virtual machine based on a CloudStack platform, which are used to improve the efficiency of creating a virtual machine under the CloudStack platform.

[0030] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of a method for creating a virtual machine based on the CloudStack platform in an embodiment of the present invention includes:

[0032] 101. Create a target PowerShell process pool using a preset compiled language, and the target PowerShell process pool is used to call instructions;

[0033] It is understandable that the execution subject of the present invention may be a virtual machine creation device based on the CloudStack platform, or may be a terminal or a server, which is not specifically limited here. The embodiment of the present invention is described by taking a server as the execution subject as an example.

[0034] It should be noted that PowerShell is a task automation and configuration management framework, and is further understood as a command line instruction and scripting environment that enables command line users and script writers to take advantage of .NET Framework and .NET Core functions. In PowerShell, management tasks are usually performed by cmdlets, which can be assembled into scripts, executable files (usually stand-alone applications), or instantiated through regular .NET classes (or WMI / COM objects), and PowerShell runs data from different storage locations to establish a resource manager or registry. In this application, a PowerShell process pool is created using the preset editing language Java to build an instruction library for calling virtual machines.

[0035] It is further explained that the process is the basis of the operating system structure, which is an executing program or a program instance running in the computer. When the server processes the process, it can assign the process to the processor and execute it by the processor, and the execution is displayed in a single order. The process pool is a technical application composed of resource processes and management processes. Among them, the resource process creates idle processes in advance, and the resource process will distribute the processes to be processed to the idle process for processing, while the management process is responsible for creating resource processes, handing over the processes to be processed to the idle resource process for processing or recycling the resource processes that have been processed. The process pool can store programs prepared in advance. When the server needs to call a program, it can directly convert the state of the program from the ready state to the execution state to realize the execution of the program.

[0036] 102. Call the target PowerShell process pool to detect whether the basic information data in the CloudStack platform is the preset configuration information data;

[0037] It is understandable that CloudStack is an open source cloud computing platform with high availability and scalability, and is also an open source cloud computing solution. It can accelerate the deployment, management, and configuration of highly scalable public and private clouds (IaaS). Using CloudStack as a foundation, data center operators can quickly and easily create cloud services through existing infrastructure.

[0038] Here, the server needs to use the preset editing language to call the PowerShell process pool to detect whether the CloudStack platform is available. Specifically, the server will call the detection program in the PowerShell process pool through the Java language, and change the state of the detection program from ready to execution, so as to detect whether the various resources in the CloudStack platform are available, that is, whether the basic information data is the same as the preset configuration information data. Among them, the resource indicators detected by the server can be: registered name, machine domain account, instruction storage address, network connectivity, etc.

[0039] It should be emphasized that in order to further ensure the security of the basic information data in the above-mentioned CloudStack platform, the basic information data in the above-mentioned CloudStack platform can also be stored in a blockchain node.

[0040] 103. If the basic information data in the CloudStack platform is preset configuration information data, connect the CloudStack platform to the preset database according to the basic information data in the CloudStack platform, and create a virtual machine basic template according to the basic information data;

[0041] When the server detects that the basic information data in the CloudStack platform is the preset configuration information data, the server needs to connect the CloudStack platform to the preset database so that the CloudStack platform can call data from the preset database.

[0042] It is further explained that the preset database here refers to a dynamic link library (dll), which is a library containing codes and data that can be used by multiple programs at the same time. In the existing technology of creating virtual machines using cloud desktops, the connection management mode of the dll database is the VM Center (a type of virtual machine center) mode, while in this application, the server uses the CloudStack mode. Therefore, the server needs to change the management and operation and maintenance data in the dll database, among which the data items changed to the CloudStack connection mode are: power on / off data, restart data, destruction data, etc.

[0043] When using the CloudStack platform to create virtual machines, there is a large amount of public data. For example, the network configuration parameters and storage data addresses of each virtual machine are the same. In order to improve the efficiency of creating virtual machines, the server uses the basic information in the CloudStack platform to create a basic template for the virtual machine.

[0044] 104. Obtain a creation request, and based on the creation request and the target PowerShell process pool, call the virtual machine basic template and preset component scheduling data to create a virtual machine.

[0045] The server obtains a creation request for creating a virtual machine input by the user, uses the creation request and the target PowerShell process pool to call the virtual machine basic template and preset component scheduling data, fills the creation information into the virtual machine basic template, and generates a virtual machine.

[0046] It should be noted that the preset component scheduling data here is the preset parameter information mounted on the hard disk outside the computer. The preset component scheduling data is to incorporate the created virtual machine into the scheduling system of the Citrix (desktop virtualization) component, and enable the created virtual machine to be normally registered and used in the domain. Only virtual machines that are normally registered in the domain can be normally connected to the intranet of the domain controller.

[0047] In the embodiment of the present invention, a target PowerShell process pool is created by using a preset compiled language, and then the target PowerShell process pool is called to connect the CloudStack platform and a preset database, thereby creating a virtual machine basic template, and finally using the virtual machine basic template and preset component scheduling data to create a virtual machine, thereby improving the efficiency of creating virtual machines under the CloudStack platform.

[0048] See also Figure 2 Another embodiment of the method for creating a virtual machine based on the CloudStack platform in the embodiment of the present invention includes:

[0049] 201. Using a preset compiled language to create a target PowerShell process pool, the target PowerShell process pool is used to call instructions;

[0050] Specifically, the server first uses a preset compiled language to create a process pool constructor to obtain an initial PowerShell process pool and start the initial PowerShell process pool; secondly, the server uses a preset compiled language to create a signal processing pipeline function in the initial PowerShell process pool, sets standard parameters of the initial PowerShell process pool, sets a working directory of the initial PowerShell process pool, returns an environment string mapping map of the initial PowerShell process pool, and sets property parameters of the initial PowerShell process pool to obtain a basic PowerShell process pool; then, in the basic PowerShell process pool, the server loads a virtual machine plug-in through a preset compiled language to input preset virtual machine parameter data and call a function to obtain a configured PowerShell process pool; finally, the server converts the state of a call instruction in the configured PowerShell process pool to a ready state to obtain a target PowerShell process pool, which is used for calling instructions.

[0051] Based on the high availability and cross-platform nature of Java, the preset compiled language used in this application is Java. In the prior art, when the Java preset compiled language performs related operations with PowerShell, the program instructions are mainly processed by Java generating a ps file, and the ps file is run in the cmd running mode. In the actual application of cloud desktops, since the steps of creating a virtual machine need to be divided and the program instructions need to be continuously operated, but the results of each step of operating the program instruction in the middle are uncertain, the method of generating a ps file using Java is not applicable. Therefore, this application uses Java to build a PowerShell process pool to process the program instructions.

[0052] When creating a target PowerShell process pool using the preset compiled language Java, the server first creates a process pool constructor. The process pool constructor provides a method for starting and managing processes (applications). Each process instruction generated by the process pool constructor can manage a process attribute set. Thus, the initial PowerShell process pool can be obtained. Then the initial PowerShell process pool is started. The server uses the preset compiled language Java to create a signal processing pipeline function, set the standard parameters of the initial PowerShell process pool, set the working directory of the initial PowerShell process pool, return the environment string map of the initial PowerShell process pool, and set the attribute parameters of the initial PowerShell process pool to obtain the basic PowerShell process pool. Some creation and setting instructions are as follows:

[0053] List <string>command() / / Returns the operating system program and parameters of the initial PowerShell.

[0054] ProcessBuilder command(List <string>command) / / Set the operating system program and parameters of the initial PowerShell process pool.

[0055] ProcessBuilder command(String...command) / / Set the operating system program and parameters of the initial PowerShell process pool.

[0056] Filedirectory() / / Returns the working directory of the initial PowerShell process pool.

[0057] ProcessBuilder directory(Filedirectory) / / Set the working directory of the initial PowerShell process pool.

[0058] Map<String,String> environment() / / Returns a string map view of the initial PowerShell process pool environment.

[0059] ProcessBuilder redirectErrorStream(boolean redirectErrorStream) / / Set the redirectErrorStream property of the initial PowerShell process pool.

[0060] After the server generates the basic PowerShell process pool, it loads the virtual machine plug-in through the preset compilation language Java to input the preset virtual machine parameter data and call the function to obtain the configuration PowerShell process pool. Here, the virtual machine plug-in refers to the Citrix plug-in, which extends the service life of the network infrastructure and improves the security of the network environment. Then, in the configuration PowerShell process pool, the state of the call instruction is converted to the ready state to obtain the target PowerShell process pool, which is used for the call instruction. It can be understood that when the server processes the relevant instructions in the PowerShell process pool, the server randomly selects a call instruction with a ready state from the PowerShell process pool, changes the state of the call instruction to execution, and completes the creation of the target PowerShell process pool for the call instruction. If there is no process in the target PowerShell process pool available when the server requests the call instruction, the server waits for 2 seconds and tries again, and starts a new call instruction to add to the PowerShell process pool.

[0061] It is further explained that the call instruction constantly changes its running state in the process pool. Generally, a call instruction has the following three basic states:

[0062] (1) Ready state

[0063] When a call instruction has been allocated all necessary resources except the central processing unit (CPU), it can be executed immediately as long as a processor is obtained. At this time, the state of the call instruction is ready.

[0064] (2) Execution (Running) status

[0065] When the call instruction has been assigned to the CPU and is being executed on the processor, the state of the call instruction is called the execution state.

[0066] (3) Blocked state

[0067] When a call instruction is being executed but cannot be executed due to waiting for a certain event to occur, the CPU is abandoned and the process is blocked. There are many events that may cause the process to be blocked, such as waiting for I / O to complete, requesting a buffer that cannot be satisfied, waiting for a letter (signal), etc.

[0068] During the execution of the call instruction, it continuously switches from one state to another. It can be in the ready state and the execution state multiple times, or it can be in the blocked state multiple times. The three states of the call instruction and their transitions are as follows:

[0069] (1) The ready state changes to the execution state

[0070] When the call instruction is in the ready state, after the process scheduler allocates a processor to it, the state of the call instruction changes from the ready state to the execution state.

[0071] (2) The execution state changes to the ready state

[0072] When the call instruction is in the execution state, the processing period of the process has satisfied the time slice allocated to the process by the processor, so the processor needs to be released, and the state of the call instruction changes from the execution state to the ready state.

[0073] (3) The execution state changes to the blocking state

[0074] When a call instruction being executed cannot continue to execute because it is waiting for a certain event to occur, the state of the call instruction changes from the execution state to the blocking state.

[0075] (4) The blocked state changes to the ready state

[0076] When the call instruction is in the blocking state, if the event it is waiting for has occurred, the state of the call instruction changes from the blocking state to the ready state.

[0077] 202. Call the target PowerShell process pool to detect whether the basic information data in the CloudStack platform is the preset configuration information data;

[0078] Specifically, the server obtains basic information data in the CloudStack platform; the server calls the detection instructions and preset environment configuration parameters in the target PowerShell process pool, and determines whether the basic information data in the CloudStack platform is the preset configuration information data through the open interface of the CloudStack platform.

[0079] Here, the basic information data in the CloudStack platform includes the registration name, machine domain account, instruction storage address, network connectivity, storage data in the cloud desktop environment, the network environment of the cloud desktop, system image, CPU configuration parameters of the virtual machine configuration, etc. Specifically, the server will use the preset compilation language Java to call the detection instructions in the target PowerShell process pool and the preset environment configuration parameters set in advance in the target PowerShell process pool, convert the state of the detection program from ready to execution, and then detect whether the basic information data is the same as the preset configuration information data through the open interface of the target CloudStack platform.

[0080] It should be emphasized that in order to further ensure the security of the basic information data in the above-mentioned CloudStack platform, the basic information data in the above-mentioned CloudStack platform can also be stored in a blockchain node.

[0081] 203. If the basic information data in the CloudStack platform is preset configuration information data, connect the CloudStack platform to the preset database according to the basic information data in the CloudStack platform, and create a virtual machine basic template according to the basic information data;

[0082] Specifically, if the basic information data in the CloudStack platform is preset configuration information data, the server obtains the original connection management data of the preset database, and rewrites the original connection management data according to the target connection management data of the CloudStack platform; the server connects the CloudStack platform to the preset database through the target connection management data; the virtual machine initial template is called in the preset database, the server obtains the basic information data, and inputs the basic information data into the virtual machine initial template to create a virtual machine basic template, the basic information data includes name configuration information, storage configuration information, network configuration information and graphic configuration information.

[0083] When the server is checking the basic information data in the CloudStack platform, it is checking the availability of the CloudStack platform's storage address and network environment in the basic information data. Only when the CloudStack platform is in an available state, that is, when the basic information data is the same as the preset configuration information data, will the server proceed to the next step and connect the CloudStack platform to the preset database.

[0084] It should be noted that the pre-set database here refers to the dynamic link library dll, which is a library containing codes and data that can be used by multiple programs at the same time. In the existing technology of creating virtual machines using cloud desktops, the connection management mode of the dll database is the VM Center (a type of virtual machine center) mode, while in this application, the server uses the CloudStack mode. Therefore, the server needs to change the management and operation and maintenance data in the dll database, among which the data items changed to the CloudStack connection mode are: power on / off data, restart data, destruction data, etc.

[0085] It is further explained that the basic information data also contains some basic data for creating virtual machines. By inputting these basic information data into the initial template of the virtual machine, a basic template of the virtual machine can be generated. When the server needs to generate a virtual machine, it can directly call the basic template of the virtual machine, which improves the efficiency of creating virtual machines. The basic data that also exists in the above basic information data are as follows:

[0086] (1) Name configuration information: the name of the virtual machine (must be globally unique), the memory size of the virtual machine (in MB), the number of VCPUs, and CPU characteristics.

[0087] (2) Storage configuration information: specifies the storage device and its properties, location and attributes, etc. Common options are:

[0094] sparse: The disk image uses a sparse format, that is, space of the specified size is not allocated immediately.

[0095] (3) Network configuration information: specifies the network type and interface properties of the network interface, such as MAC address, driver mode, etc. Common options are:

[0096] bridge=BRIDGE: connects to the bridge device named "BRIDEFG";

[0097] network=NAME: connect to the network named "NAME";

[0098] model: the network device number seen in GuestOS, such as e1000, rtl8139 or virtio, etc.

[0099] mac: Fixed MAC address; a random address will be used if this option is omitted, but in either case, for KVM, the first three segments must be 52:54:00.

[0100] (4) Graphics configuration information: defines the configuration related to the virtual machine display function, such as VNC related configuration. Common options are:

[0101] TYPE: specifies the display type, which can be vnc, sdl, soice or none. The default is vnc.

[0103] listen: The IP address that the server listens to when TYPE is vnc or spice. The default is 127.0.0.1, which can be modified in / etc / libvirt / qemu;

[0104] password: When TYPE is vnc or spice, specify the authentication password for remote access to the listening service.

[0105] 204. Obtain a creation request, and based on the creation request and the target PowerShell process pool, call the virtual machine basic template and preset component scheduling data to create a virtual machine;

[0106] Specifically, the server first obtains a creation request and extracts virtual machine creation information from the creation request; secondly, the server uses a preset compiled language to call the target PowerShell process pool, creates a configuration directory, and inputs the virtual machine creation information into the configuration directory, where the configuration directory is used to record the name and domain account of the virtual machine; then the server binds the configuration directory to the virtual machine basic template to obtain the virtual machine configuration template; finally, the server obtains preset component scheduling data in a preset external mount component, uses a preset compiled language to call the target PowerShell process pool, inputs the preset component scheduling data into the virtual machine configuration template, and creates a virtual machine.

[0107] The server obtains a creation request for creating a virtual machine input by the user, and obtains virtual machine creation information corresponding to the virtual machine to be created from the creation request. The virtual machine creation information here includes: virtual machine creation name, virtual machine domain account, etc., and then enters the virtual machine creation information into the configuration directory. The configuration directory here is an empty computer directory established by using the Java preset compilation language to call the process instruction in the target PowerShell process pool. The server fills the virtual machine creation information into the configuration directory, and completes the generation of the configuration directory.

[0108] It should be noted that the server binds the configuration directory to the virtual machine basic template to obtain the virtual machine configuration template. Finally, the server obtains the preset component scheduling data in the preset external mounting component, uses the preset compilation language to call the target PowerShell process pool, and inputs the preset component scheduling data into the virtual machine configuration template to generate a virtual machine. The preset component scheduling data here is the preset parameter information mounted on the hard disk outside the computer. The preset component scheduling data is to incorporate the created virtual machine into the scheduling system of the citrix (desktop virtualization) component, and to enable the created virtual machine to be registered and used normally in the domain. Only virtual machines that are normally registered in the domain can be normally connected to the intranet of the domain controller.

[0109] 205. When the CloudStack platform fails to successfully create the virtual machine, a rollback request is obtained, and the rollback is implemented in a preset background instruction box according to the location address in the rollback request.

[0110] Specifically, when the CloudStack platform fails to successfully create a virtual machine, the server obtains a rollback request and extracts the location address to be rolled back from the rollback request; the server inputs the location address into a preset rollback instruction, obtains a target instruction, and executes the target instruction in a preset background instruction box to implement the rollback of the target instruction.

[0111] Rollback refers to the act of restoring program instructions or data to the most recent correct hash value in the database when a program instruction or data error occurs. During the rollback process, it is necessary to specify which correct hash value to roll back to. Generally, the rollback is performed by rolling back program instructions through a rollback request input by the user. It should be noted that the rollback request contains the location address (hash value) of the required rollback. The server performs the rollback operation through the rollback instruction. The rollback instruction is: git instruction. The location address is input into the rollback instruction to obtain the target instruction. Then the server executes the target instruction in the preset background instruction box to complete the rollback request.

[0112] For example, the target instruction is git reset hard commit-id, which means that all program instructions after the location address commit-id will be deleted, that is, the program instructions will be rolled back to the position of commit-id.

[0113] In the embodiment of the present invention, a target PowerShell process pool is created by using a preset compiled language, and then the target PowerShell process pool is called to connect the CloudStack platform and a preset database, thereby creating a virtual machine basic template, and finally using the virtual machine basic template and preset component scheduling data to create a virtual machine, thereby improving the efficiency of creating virtual machines under the CloudStack platform.
