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.

[0034] Introduction to terms involved in this application:

[0035] Kubernetes (k8s): An open source container orchestration system for automating the deployment, scaling, and management of application containers.

[0036] KubeVirt: A virtualization extension component, a Kubernetes virtualization extension that uses the Kubernetes API (application programming interface) to manage the life cycle of virtual machines.

[0037] Virtual Machine (VM): A system in which software emulates a physical computer and can run an operating system and application programs.

[0038] IO Errors: Errors that may occur during input / output (IO) operations. These errors may be caused by hardware failure, driver problems, or file system corruption.

[0039] Libvirt: Virtualization management software, an open source API (application programming interface) library for interacting with virtualization technologies (such as KVM, Xen) and managing virtual machines.

[0040] Event mechanism: A feature in Kubernetes that is used to notify users of status changes that occur in the cluster, such as node failures and Pod restarts.

[0041] Disk IO error detection: refers to monitoring and identifying errors in disk input and output operations during the operation of the virtual machine.

[0042] The virtual machine disk input and output error detection and processing method provided in the embodiment of the present application can be executed by a server, which can be a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The server can communicate with the terminal through the network. The terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc.

[0043] like Figure 1 As shown, a k8s cluster can deploy the virtualization extension component KubeVirt, and a virtual machine VM definition can be created through the virtualization extension component KubeVirt. The virtual machine VM can use the disk DISK of the edge k8sworker working node of each k8s cluster as the virtualized disk of the virtual machine. The virtual machine disk input and output error detection and processing method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown.

[0044] In an exemplary embodiment, Figure 2 As shown, a method for detecting and processing virtual machine disk input and output errors is provided, which can be applied to Figure 1 The edge k8s worker node and other cluster nodes in the method may include the following steps:

[0045] Step S201: receiving disk event information sent by a virtual machine of a cluster node through an application programming interface of virtualization management software through a disk input / output event system module.

[0046] In this step, a disk input and output event system (DiskIOEventSystem) module can be implemented. This disk input and output event system (DiskIOEventSystem) module registers the application programming interface (Libvirt API) of the virtualization management software and receives and sends disk event information such as IO error events and IO error causes, including event information of the virtualized disks of the virtual machines of the cluster nodes.

[0047] The disk input and output event system (DiskIOEventSystem) is deployed on the cluster nodes as a service daemon DaemonSet, which can be included on each edge k8s worker node. It can receive events sent to it by all virtual machines on the node through the application programming interface (Libvirt API) of the virtualization management software.

[0048] Among them, through the application programming interface (Libvirt API) of virtualization management software such as:

[0049] virtConnectDomainEventIOErrorCallback;

[0050] virtConnectDomainEventIOErrorReasonCallback;

[0051] The IO Error event of the virtualized disk can be registered by a third-party component to receive notification.

[0052] Specifically, the disk input and output event system module (DiskIOEventSystem) run by each edge k8s worker node can receive disk event information sent by the virtual machine of the edge k8s worker node (corresponding cluster node) through the application programming interface (Libvirt API) of the virtualization management software, which may include disk event information such as disk IO errors and error causes.

[0053] Step S202: Send the disk event information to the cloud console through the disk input and output event system module. The console is used to execute the corresponding error handling process according to the disk event information.

[0054] Combination Figure 3 , through the DiskIOEventSystem module, the disk event information (which may include disk IO error information, error causes, etc.) is sent to the cloud console (WEB console). The cloud console can be used by Web console administrators to manage virtual machine operations. The cloud console (WEB console) can customize the automated error handling process (error handling strategy), for example, it can automatically execute the corresponding error handling process based on the disk event information based on predefined rules, such as restarting the virtual machine or isolating the faulty disk, etc., which can reduce manual intervention.

[0055] The virtual machine disk input and output error detection and processing method of this embodiment receives the disk event information sent by the virtual machine of the cluster node through the application programming interface of the virtualization management software through the disk input and output event system module; the disk input and output event system module is deployed on the cluster node in the form of a service daemon process; the disk input and output event system module registers the application programming interface of the virtualization management software; the disk event information includes the event information of the virtualized disk of the virtual machine of the cluster node; the disk event information is sent to the cloud console through the disk input and output event system module; the console is used to execute the corresponding error processing process according to the disk event information. This scheme can monitor the disk input and output operation in real time at each cluster node using the application programming interface of the virtualization management software, and can generate disk event information when the virtual machine disk input and output error is detected, and then based on the event-driven characteristics of the cluster, the disk event information is reported to the cloud console at the cluster node, and the cloud console can set the error processing process, and automatically execute the corresponding error processing process according to the disk event information, thereby improving the detection and processing efficiency of the virtual machine disk input and output errors.

[0056] In an exemplary embodiment, sending the disk event information to the cloud console through the disk input and output event system module in step S202 may include:

[0057] The disk input and output event system module writes the disk event information into the event defined by the custom resource of the virtual machine instance of the cluster node; and sends the disk event information to the cloud console through the event mechanism defined by the custom resource of the virtual machine instance of the cluster node.

[0058] In this embodiment, combined with Figure 4 , the application programming interface (Libvirt API) of the virtualization management software can register and subscribe to the detected disk event information (DISK IO Error) through the disk input and output event system (DiskIOEventSystem) module and receive the disk event information in real time. The disk input and output event system (DiskIOEventSystem) module can write the received disk event information into the event of the virtual machine instance custom resource definition (VMI CRD) of the edge k8s worker working node, and send the disk event information to the cloud console through the event mechanism of the virtual machine instance custom resource definition (VMI CRD) of the edge k8s worker working node. Through this event mechanism, external high-availability operations can also be triggered, such as restarting the virtual machine, triggering the cloud alarm mechanism and other external workflows.

[0059] In an exemplary embodiment, the method may further include: creating a virtual machine through a virtualization extension component deployed in a cluster, and using a disk of a cluster node as a virtualized disk of the virtual machine.

[0060] In this embodiment, Figure 1 As shown, the virtualization extension component KubeVirt can be used in the k8s cluster to provide virtual machines. A k8s cluster can deploy the virtualization extension component KubeVirt. Virtual machines can be created through the virtualization extension component KubeVirt deployed in the k8s cluster. The virtual machines can use the physical disk DISK of the edge k8s worker node of each k8s cluster as the virtualized disk of the virtual machine. The physical disk DISK of the edge k8s worker node can be virtualized and mounted to the virtual machine for use as a system disk and data disk.

[0061] In an exemplary embodiment, the console may also be used to display location information of the corresponding virtual machine and virtualized disk according to the disk event information.

[0062] In this embodiment, Figure 3 As shown, the cloud console can also be used to display the location information of the virtual machine and virtualized disk corresponding to the disk event information based on the disk event information containing the cluster's disk input and output error events and their error causes. This allows Web console administrators to view the cluster's disk input and output error events and their error causes, and locate specific virtual machines and virtualized disks, which can be used to quickly locate and troubleshoot errors.

[0063] In an exemplary embodiment, the cluster node includes a k8s cluster node. The k8s cluster node may include an edge k8s worker node of the k8s cluster.

[0064] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0065] Based on the same inventive concept, the embodiment of the present application also provides a virtual machine disk input and output error detection and processing device for implementing the virtual machine disk input and output error detection and processing method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the one or more virtual machine disk input and output error detection and processing device embodiments provided below can refer to the limitations of the virtual machine disk input and output error detection and processing method above, and will not be repeated here.

[0066] In one embodiment, a cluster system is provided, the system comprising: a cluster node and a cloud console connected in communication. The cluster node can be used to execute the virtual machine disk input and output error detection processing method of the above embodiment. Figure 3 As shown, the cluster node may include an edge k8s worker node of the k8s cluster.

[0067] On the whole, this application can detect and report virtual machine disk input and output errors through the Kubernetes event mechanism and the application programming interface (LibvirtAPI) of the virtualization management software when managing virtual machines using the virtualization extension component KubeVirt in a Kubernetes cluster environment. It can make full use of the event-driven characteristics of Kubernetes and combine the management capabilities of the virtualization extension component KubeVirt for virtual machines to achieve rapid and automated detection and processing of virtual machine disk input and output errors.

[0068] This application can monitor the input and output status of virtual machine disks in real time, so that when input and output errors occur, they can be detected and responded to immediately, and predefined processing processes can be automatically triggered to reduce manual intervention. By using the event mechanism of Kubernetes and the virtual machine management capabilities of the virtualization extension component KubeVirt, seamless integration with cloud native environments can be achieved. By quickly detecting and processing input and output errors, virtual machine failures caused by disk problems can be reduced, and the reliability and stability of the entire system can be improved. When input and output errors are detected, it is helpful to take timely measures to protect data, prevent data loss or damage, and ensure that appropriate security measures are taken during event processing and automated response to prevent potential security risks. Through centralized management and automated response, input and output error events from all nodes in the cluster can be received, processed and responded to, improving the efficiency of the operation and maintenance team in handling disk input and output errors, allowing administrators to customize the functions of automated response strategies according to specific needs, and improving the flexibility and adaptability of the system. It can adapt to Kubernetes clusters of different sizes, meet the needs of small-scale development environments to large-scale production environments, and ensure compatibility with different storage solutions, including local storage, network attached storage (NAS) and storage area networks (SAN).
