[0038] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0040] The main solution of the present application is: to obtain the current status information of the virtual machine in real time through SCVMM, and determine whether the virtual machine is in an abnormal state based on the current status information; if the virtual machine is in an abnormal state, determine the cause of the abnormality of the virtual machine; determine the repair strategy corresponding to the virtual machine based on the cause of the abnormality, and perform repair operations on the virtual machine based on the repair strategy.

[0041] At present, as the enterprise infrastructure shifts from traditional local deployment to cloud deployment, cloud computing platform-based solutions have become the needs of enterprise management to meet business strategies. Virtualization technology has expanded the utilization efficiency of hardware. Through CPU virtualization and virtualization of peripheral components such as IO devices, a physical machine is allowed to run multiple virtual server units at the same time, which significantly improves computer work efficiency while also bringing about a massive increase in server management objects.

[0042] With the widespread application of virtualization technology, the stability and reliability of virtual machines have become key factors. HyperV is a virtualization technology launched by Microsoft. The private cloud of the Hyper-V technology stack consists of four parts: computing, storage, network and management. Management is mainly composed of components such as AD, SCVMM, SCOM and SOM. SCVMM stands for System Center Virtual Machine Manager, which is a solution for managing virtualized data centers. Through it, users can configure and manage virtual hosts, storage and computing resources, and provide management pages for virtual machines and related services. When administrators manage virtual machines through SCVMM, the operation of the virtual machines will fail due to abnormal virtual machine status.

[0043] Virtual machines are efficiently managed through SCVMM (System Center Virtual Machine Manager). However, due to the instability of the underlying environment, virtual machines may encounter various abnormal states, such as Paused, Incomplete VM Configuration, Host Not Responding, Missing, Updatefailed, Migration Failed, etc. These abnormal states will cause virtual machine operation failures and affect business continuity. Therefore, how to detect virtual machine anomalies and repair anomalies is a problem that needs to be solved urgently.

[0044] This application obtains the status information of the virtual machine in real time through SCVMM, performs abnormal detection of the virtual machine based on the status information, performs repair operations on the virtual machine according to the repair strategy corresponding to the cause of the abnormality of the virtual machine, and then automatically repairs the virtual machine in different ways according to different abnormal states. Then, through the automatic discovery and repair tool of the abnormal state of the virtual machine managed by SCVMM, the problem of being unable to operate the virtual machine due to the abnormal state of the virtual machine is solved, so as to achieve the purpose of automated management of the operation and maintenance of massive virtual machines.

[0045] It should be noted that the execution subject of this embodiment may be an abnormality detection and recovery device of a virtual machine, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an abnormality detection and recovery device of a virtual machine capable of realizing the above functions, etc., and this embodiment does not specifically limit this. The following takes the abnormality detection and recovery device of a virtual machine as an example of the execution subject to explain this embodiment and the following embodiments.

[0046] Based on this, the present application proposes a first embodiment of a virtual machine abnormality detection and recovery method, please refer to Figure 1 The abnormality detection and recovery method of the virtual machine includes steps S101 to S103:

[0047] Step S101, obtaining the current state information of the virtual machine in real time through the SCVMM, and determining whether the virtual machine is in an abnormal state based on the current state information;

[0048] In this embodiment, an automated discovery and repair tool for abnormal states of virtual machines managed by SCVMM can be deployed, and a program corresponding to the abnormal detection and recovery method for virtual machines in this application is executed when the virtual machines are running. The tool is implemented using PowerShell commands to automatically discover virtual machines in abnormal states, and use different methods to repair the abnormalities of virtual machines according to different abnormal states, so as to fill the gap in automated repair of abnormal states of virtual machines under the HyperV technology stack, avoid situations where users or administrators are unable to operate virtual machines due to abnormal states of virtual machines, and enhance the automated management capabilities of operation and maintenance of massive virtual machines under the HyperV technology stack.

[0049] In this embodiment, during the operation of the virtual machine, the current status information of the virtual machine is obtained in real time through the SCVMM, that is, by interacting with the interface of the SCVMM, the current status information of all virtual machines managed by the SCVMM is obtained in real time.

[0050] After obtaining the current state information of each virtual machine, for each virtual machine, it is determined whether the virtual machine is in an abnormal state based on the current state information; specifically, in a feasible implementation, step S101 may include steps S1011 to S1012:

[0051] Step S1011, comparing the current state information with a preset normal state corresponding to the virtual machine to determine whether the current state information matches the preset normal state;

[0052] Step S1012: If the current state information does not match the preset normal state, it is determined that the virtual machine is in an abnormal state.

[0053] In this embodiment, a preset normal state corresponding to each virtual machine is pre-set, and the preset normal state can be a state label. After obtaining the current state information of each virtual machine, for each virtual machine, the current state information of the virtual machine is compared with the preset normal state of the virtual machine to determine whether the current state information matches the preset normal state, that is, to determine whether the current state information of the virtual machine is consistent with the preset normal state of the virtual machine.

[0054] If the current status information of the virtual machine matches the preset normal state of the virtual machine, it is determined that the virtual machine is in a normal state. If the current status information of the virtual machine does not match the preset normal state of the virtual machine, it is determined that the virtual machine is in an abnormal state, thereby accurately determining which virtual machines are in an abnormal state among all virtual machines managed by SCVMM.

[0055] Step S102, if the virtual machine is in an abnormal state, determining the abnormal cause of the virtual machine;

[0056] In this embodiment, if the virtual machine is in an abnormal state, that is, for each abnormal virtual machine in an abnormal state, the abnormal cause of the virtual machine is determined. Specifically, in a feasible implementation, step S102 may include steps S1021 to S1022:

[0057] Step S1021, if the virtual machine is in an abnormal state, obtaining log information, virtual machine configuration file, and software configuration information corresponding to the virtual machine;

[0058] Step S1023: performing log analysis on the log information, and performing configuration checking operations on the virtual machine configuration file and software configuration information to determine the abnormal cause of the virtual machine.

[0059] In this embodiment, when the virtual machine is in an abnormal state, for each abnormal virtual machine in the abnormal state, log information, virtual machine configuration file, and software configuration information corresponding to the virtual machine are obtained.

[0060] After obtaining the log information, the virtual machine configuration file and the software configuration information, an abnormality analysis of the virtual machine is performed to obtain the abnormality cause of the virtual machine, that is, log analysis is performed on the log information, and configuration checking operations are performed on the virtual machine configuration file and the software configuration information to determine the abnormality cause of the virtual machine. For example, log analysis is performed on the log information to determine whether the virtual machine has a hardware failure and / or a network problem, and configuration checking operations are performed on the virtual machine configuration file and the software configuration information to determine whether the virtual machine has a software configuration error and / or a virtual machine configuration file abnormality, etc. If there is at least one of the abnormalities such as hardware failure, software configuration error, network problem and virtual machine configuration file abnormality, log analysis is performed on the log information, and / or configuration checking operations are performed on the virtual machine configuration file and the software configuration information to obtain the abnormality cause of the virtual machine, wherein the abnormality cause includes virtual machine configuration loss, underlying storage failure, virtual machine configuration damage and virtual machine loss.

[0061] Step S103: determining a repair strategy corresponding to the virtual machine based on the abnormality cause, and performing a repair operation on the virtual machine based on the repair strategy.

[0062] In this embodiment, after determining the cause of the abnormality of the virtual machine, the repair strategy corresponding to the virtual machine is determined based on the cause of the abnormality, and the repair operation of the virtual machine is performed based on the repair strategy, so that different methods are used to automatically repair the virtual machine for different abnormal states. For example, if the cause of the abnormality is the loss of the virtual machine, the repair strategy is to restart the virtual machine, and then restart the virtual machine during the repair operation of the virtual machine to achieve the repair of the virtual machine.

[0063] In a feasible implementation, after step S103, the abnormality detection and recovery method of the virtual machine may further include step S104:

[0064] Step S104, obtaining a repair log corresponding to the repair operation, and storing the abnormal state, abnormal cause, repair strategy and repair log in association.

[0065] In this embodiment, after the virtual machine repair is completed, the repair log corresponding to the repair operation is obtained. Specifically, the log corresponding to the repair operation in the log information of the virtual machine is used as the repair log, and the abnormal state, abnormal cause, repair strategy and repair log are stored in association for subsequent problem analysis and system optimization, thereby reducing the probability of abnormal occurrence of the virtual machine.

[0066] It should be noted that, during the process of performing the repair operation on the virtual machine, the execution status of each step in the repair operation is monitored in real time, and whether the repair operation is successfully performed is determined according to the execution status to ensure the smooth progress of the repair operation.

[0067] The method for detecting and recovering an abnormality of a virtual machine proposed in the present embodiment obtains the current status information of the virtual machine in real time through SCVMM, and determines whether the virtual machine is in an abnormal state based on the current status information; then, if the virtual machine is in an abnormal state, determines the cause of the abnormality of the virtual machine; then, determines the repair strategy corresponding to the virtual machine based on the cause of the abnormality, and performs a repair operation on the virtual machine based on the repair strategy, obtains the status information of the virtual machine in real time through SCVMM, performs abnormality detection of the virtual machine based on the status information, performs a repair operation on the virtual machine based on the repair strategy corresponding to the cause of the abnormality of the virtual machine, and then automatically repairs the virtual machine in different ways according to different abnormal states, and then, through the automatic discovery and repair tool for the abnormal state of the virtual machine managed by SCVMM, solves the problem of being unable to operate the virtual machine due to the abnormal state of the virtual machine, so as to achieve the purpose of automated management of the operation and maintenance of massive virtual machines.

[0068] In a feasible implementation, step S103 may include steps a1 to a2:

[0069] Step a1: if the abnormality is caused by the loss of virtual machine configuration, performing a migration operation on the virtual machine based on the repair strategy;

[0070] Step a2: When the migration operation is completed, a refresh operation is performed on the virtual machine.

[0071] In this embodiment, if the cause of the exception is the loss of virtual machine configuration, the repair strategy is virtual machine migration and refresh. Then, when the repair operation is performed on the virtual machine based on the repair strategy, the migration operation is performed on the virtual machine based on the repair strategy. When the migration operation is completed, the refresh operation is performed on the virtual machine. After the refresh operation is completed, it is determined that the virtual machine repair is completed. Then, when the repair operation is performed on the virtual machine, the virtual machine is migrated and refreshed to achieve the repair of the virtual machine.

[0072] In a feasible implementation, step S103 may include steps b1 to b2:

[0073] Step b1: if the abnormality is caused by an underlying storage failure, restarting the virtualization management component corresponding to the virtual machine;

[0074] Step b2: restarting the virtual machine when the virtualization management component is restarted, and performing a refresh operation on the virtual machine when the virtual machine is restarted.

[0075] In this embodiment, if the cause of the exception is an underlying storage failure, the repair strategy is to restart the virtualization management component, restart the virtual machine, and refresh it. Then, when the repair operation is performed on the virtual machine based on the repair strategy, the virtualization management component corresponding to the virtual machine is restarted first. When the virtualization management component is restarted, the virtual machine is restarted. When the virtual machine is restarted, a refresh operation is performed on the virtual machine. After the refresh operation is completed, it is determined that the virtual machine repair is completed. Then, when the repair operation is performed on the virtual machine, the virtualization management component is restarted, the virtual machine is restarted and refreshed to achieve the repair of the virtual machine.

[0076] In a feasible implementation, step S103 may include steps c1 to c3:

[0077] Step c1, if the abnormality is caused by a damaged virtual machine configuration, performing a repair operation on the virtual machine, and determining whether the virtual machine is successfully repaired when the repair operation is completed;

[0078] Step c2, when the virtual machine is not repaired successfully, performing a migration operation on the virtual machine, and when the migration operation is completed, performing a refresh operation on the virtual machine;

[0079] Step c3: when the refresh operation is completed, perform a repair operation on the virtual machine.

[0080] In this embodiment, if the cause of the exception is the damage to the virtual machine configuration, the repair strategy is to repair, migrate if the repair is not successful, refresh and then repair. Then, when the repair operation is performed on the virtual machine based on the repair strategy, the repair operation is first performed on the virtual machine, and when the repair operation is completed, it is determined whether the virtual machine is repaired successfully.

[0081] Next, when the virtual machine is not repaired successfully, a migration operation is performed on the virtual machine, and when the migration operation is completed, a refresh operation is performed on the virtual machine. When the refresh operation is completed, a repair operation is performed on the virtual machine, and then during the repair operation on the virtual machine, the virtual machine is repaired, migrated if the repair is not successful, refreshed, and then repaired to achieve the repair of the virtual machine.

[0082] In a feasible implementation, step S103 may include step d1:

[0083] Step d1: If the abnormality is caused by the loss of the virtual machine, restart the virtual machine.

[0084] In this embodiment, if the cause of the abnormality is the loss of the virtual machine, the repair strategy is to restart the virtual machine, and then restart the virtual machine during the repair operation on the virtual machine to achieve the repair of the virtual machine.

[0085] The method for detecting and recovering a virtual machine abnormality proposed in this embodiment performs a migration operation on the virtual machine based on the repair strategy if the cause of the abnormality is the loss of virtual machine configuration; then, when the migration operation is completed, performs a refresh operation on the virtual machine. The virtual machine is repaired by migrating and refreshing the virtual machine during the repair operation. The problem of being unable to operate the virtual machine due to the abnormal state of the virtual machine is solved by using an automated discovery and repair tool for the abnormal state of the virtual machine managed by SCVMM, thereby achieving the purpose of automated management of the operation and maintenance of massive virtual machines.
