Description

Technical Field

[0001] The present invention relates to the field of cloud computing technology, and in particular to a virtual machine information synchronization method, device, equipment and storage medium. Background Art

[0002] With the rapid development of information technology, cloud computing has become one of the hot topics in today's science and technology field. As an emerging computing model, cloud computing realizes on-demand allocation and elastic expansion of computing power by providing computing resources to users. As the current cloud computing market continues to expand, more and more enterprises and organizations choose to migrate their businesses to the cloud, and the application and market size of cloud computing in China are showing strong growth. Among them, OpenStack, as a leading open source cloud computing platform, is widely used to build and manage public and private clouds. Through its rich set of components and services, it provides flexible and scalable Infrastructure as a Service (IaaS) solutions.

[0003] OpenStack is a combination of a series of open source components, which mainly use pooled virtual resources to build and manage private and public clouds. Among them, Keystone, Glance, Cinder, Neutron, Nova, and Placement are the main components, which are responsible for authentication and authorization, image management, block device management, network management, virtual machine management, and resource scheduling functions in the cloud management platform. Among them, the OpenStack Nova component is the core computing service component in the OpenStack project, responsible for managing and maintaining the computing resources of the cloud environment, including instance lifecycle management, scheduling and allocation of computing resources, etc. Nova achieves these functions through the collaborative work of multiple sub-components. Specifically, the Nova Scheduler module is mainly responsible for virtual machine resource scheduling. By defining different schedulers and algorithms, it determines which computing server the virtual machine is scheduled to. The OpenStack Placement component is the key component responsible for resource tracking and management in the OpenStack project. It was split from the Nova service in the Newton version and is specifically used to collect and manage the resource status and usage in the entire cloud computing environment. Through its API (Application Programming Interface) interface module, resource tracking function, working principle, project implementation and configuration, and deployment optimization, it realizes efficient management and scheduling of OpenStack cloud platform resources. However, Nova is the core computing component in the cloud management platform based on OpenStack. When Nova-Scheduler module is used to implement virtual machine scheduling, it records virtual machine-related resource information. At the same time, the Placement component responsible for resource tracking and management in the OpenStack project will also record more detailed virtual machine resource information. At this time, due to the frequent virtual machine operations and physical machine evacuation on the cloud platform, there may be inconsistencies between the virtual machine resource information recorded in Nova and the information recorded in Placement, resulting in errors in node resource scheduling and physical machine resource monitoring.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In the cloud management platform based on OpenStack, Nova implements virtual machine scheduling and records virtual machine related resource information. At the same time, the Placement component will also record more detailed virtual machine resource information. At this time, due to the frequent virtual machine operations and physical machine evacuation operations on the cloud platform, the virtual machine resource information recorded in Nova and the information recorded in Placement may be inconsistent. This application can configure periodic tasks, regularly detect and synchronize the resource information recorded in Nova to the Placement component, expand the basic management functions of the cloud platform, and ensure that the virtual machine resource related information in the Nova component of the cloud platform corresponds to the corresponding data in the Placement component, thereby ensuring data consistency.

[0043] See also Figure 1 As shown, an embodiment of the present invention discloses a virtual machine information synchronization method, which is applied to a preset cloud computing management platform, including:

[0044] Step S11: creating a virtual machine information synchronization task for the preset cloud computing management platform, and starting the virtual machine information synchronization task according to a preset resource information synchronization cycle.

[0045] In this embodiment, first, a task cycle control configuration is added to the configuration group of the configuration file of the Nova component, and the preset resource information synchronization period of the virtual machine information synchronization task is determined according to the task cycle control configuration, and then a virtual machine information synchronization task of the preset cloud computing management platform is created to start the virtual machine information synchronization task according to the above resource information synchronization period. Specifically, in this embodiment, relying on Nova's own configuration management system, the task_heal_Placement_interval configuration is added to the workarounds configuration group of the Nova.conf (configuration file) file to configure the time interval for repairing Placement resource data, that is, synchronizing Nova virtual machine resource information to the Placement component, in minutes, to trigger automated virtual machine resource information consistency detection and synchronization periodic tasks. At the same time, a function with the @periodic_task.periodic_task identifier can also be defined in the schedulermanager, indicating the definition of a periodic task to write code logic for processing the synchronization of Nova virtual machine resource information to the Placement component.

[0046] Step S12, monitor the computing node change information of the preset cloud computing management platform, and execute the virtual machine information synchronization task. Detect the Nova component and Placement component of the preset cloud computing management platform according to the computing node change information, and determine whether the corresponding computing node change information in the Nova component and the Placement component is consistent.

[0047] In this embodiment, Figure 2 As shown, before monitoring the computing node change information of the preset cloud computing management platform, it can be determined whether the current preset resource information synchronization period is greater than the preset synchronization period threshold; if the preset resource information synchronization period is greater than the preset synchronization period threshold, the step of monitoring the computing node change information of the preset cloud computing management platform is performed. According to the previous step, the default configuration of the time interval for synchronizing the Nova virtual machine resource information to the Placement component can be configured, that is, the preset synchronization period threshold is set to -1, indicating that no repair is performed, and supports configuration of integers greater than 0. Correspondingly, if the above configuration is -1, no detection is performed; if the above configuration is an integer greater than 0, the next step of the detection process is performed.

[0048] When performing consistency detection, first monitor the computing node change information of the preset cloud computing management platform, and execute the virtual machine information synchronization task to detect the Nova component and Placement component of the preset cloud computing management platform according to the computing node change information, and determine whether the corresponding computing node change information in the Nova component and the Placement component is consistent.

[0049] Step S13: If the computing node change information in the Nova component and the Placement component is consistent, run the virtual machine on the computing node of the preset cloud computing management platform, monitor the virtual machine information of the virtual machine, and record the virtual machine information to the Nova component and the Placement component.

[0050] In this embodiment, if the computing node change information in the Nova component and the Placement component is consistent, that is, Figure 2 If the consistency check of Reosurce prividers in the system passes, the virtual machine on the computing node of the preset cloud computing management platform will be run, and the virtual machine information of the virtual machine will be monitored, and the virtual machine information will be recorded in the Nova component and the Placement component. In this way, combined with the above steps, relying on the OpenStack basic architecture, based on the existing scheduled task mechanism of the Nova component, the time interval for synchronizing the Placement virtual machine resource information is configured through the Nova configuration file, and the periodic task of automatically synchronizing the virtual machine resource information is triggered to detect the consistency of the virtual machine resource information in Nova and Placement, so as to synchronize the virtual machine resource information recorded in the Nova database to the Placement.

[0051] Step S14: determine whether the virtual machine information in the Nova component is consistent with that in the Placement component, and synchronize the virtual machine information in the Nova component to the Placement component according to the determination result.

[0052] In this embodiment, Figure 2 As shown, Allocations detection is performed to determine whether the virtual machine information in the Nova component and the Placement component is consistent, and different virtual machine information in the Nova component and the Placement component is synchronized to the Placement component according to the determination result.

[0053] This embodiment can create a virtual machine information synchronization task for a preset cloud computing management platform, and add a task_heal_Placement_interval configuration in the configuration group of the configuration file to configure the time interval for synchronizing Nova virtual machine resource information to the Placement component to start the virtual machine information synchronization task, and execute the virtual machine information synchronization task by monitoring the computing node change information of the preset cloud computing management platform. According to the computing node change information, the Nova component and the Placement component of the preset cloud computing management platform are detected to determine whether the corresponding computing node change information in the Nova component and the Placement component is consistent; if the computing node change information in the Nova component and the Placement component is consistent, the virtual machine on the computing node of the preset cloud computing management platform is run, and the virtual machine information of the virtual machine is monitored, and the virtual machine information is recorded in the Nova component and the Placement component; and it is determined whether the virtual machine information in the Nova component and the Placement component is consistent, and the virtual machine information in the Nova component is synchronized to the Placement component according to the determination result. Through the above technical solution, in the cloud management platform based on OpenStack, both the Nova component and the Placement component will record the virtual machine resource information, which leads to the risk of inconsistency in the recorded information in the Nova component and the Placement component. Based on the existing periodic task mechanism of the Nova component, the periodic task is extended to realize the automatic synchronization of virtual machine resource information, and the Nova configuration file workaround group is used to increase the configuration of the automatic synchronization of virtual machine resource cycle to trigger the periodic task. In this way, by configuring the periodic task, the resource information recorded in Nova is regularly detected and synchronized to the Placement component, the existing function of the OpenStack Nova component is extended to realize the synchronization of virtual machine resource information, and the virtual machine resource related information in the cloud platform Nova component is ensured to correspond to the corresponding data in the Placement component one by one, thereby ensuring the consistency of the underlying data and improving the stability of the cloud platform scheduling, monitoring and other functions.

[0054] Based on the previous embodiment, it can be known that the present application can periodically detect the resource information in the Nova component and the Placement component by configuring a periodic task, and synchronize the resource information recorded in the Nova component to the Placement component. Next, the process of synchronizing resource information will be described in detail in this embodiment. Figure 3 As shown, the embodiment of the present application discloses a specific virtual machine information synchronization method, which is applied to a preset cloud computing management platform, including:

[0055] Step S21, monitor the computing node change information of the preset cloud computing management platform, and execute the virtual machine information synchronization task. According to the computing node change information, detect the Nova component and the Placement component of the preset cloud computing management platform, and determine whether the corresponding computing node change information in the Nova component and the Placement component is consistent.

[0056] In this embodiment, the resource information synchronization process is mainly implemented by the consistency detection module, such as Figure 4 As shown, the consistency detection module for synchronizing Nova virtual machine resource information to the Placement component mainly includes the Reosurce prividers detection module and the Allocations detection module. The Reosurce prividers detection module is used to obtain the computing node information reported in Nova, and perform consistency detection and data synchronization with the computing node information recorded in Placement; the Allocations detection module is mainly used to obtain the virtual machine information reported in Nova, including but not limited to the virtual machine uuid (Universally Unique Identifier), virtual machine specification information, virtual machine PCI (Peripheral Component Interconnect) device information, etc., and perform consistency detection and data synchronization with the allocations information recorded in Placement.

[0057] Specifically, Figure 4 As shown, firstly, a Reosurce prividers detection is performed, which can detect the first data change information of the first data table of the Nova component of the preset cloud computing management platform, and detect the second data change information of the second data table of the Placement component of the preset cloud computing management platform, and then respectively determine the first universal unique identifier of the computing node corresponding to the first data change information and the second universal unique identifier of the computing node corresponding to the second data change information, and determine whether the first universal unique identifier and the second universal unique identifier are consistent.

[0058] It is understandable that the OpenStack-based cloud management platform mainly records the information of the computing nodes that have joined the cluster through the compute_nodes data table of the Nova component. When the computing node is expanded and added to the cluster, the Nova-compute service on the corresponding node is successfully started. The first data table of the Nova database, namely the compute_node data table, records the detailed information of the computing node, including the basic information of the computing node and the CPU (Central Processing Unit), memory, disk over-provisioning ratio, CPU, memory, disk usage, CPU, memory, disk remaining, the number of virtual machines running on the computing node, and other virtual machine-related resource data. On the other hand, Placement is a key component responsible for resource tracking and management in the OpenStack project. When the computing node is expanded and added to the cluster, and the Nova-compute service on the corresponding node is successfully started, the Placement database will also record the corresponding computing node resource-related information, including initializing resource types in the resource_class data table, such as CPU, memory, disk, GPU (graphics processing unit) card, etc., and recording the corresponding data of the computing node in the second data table, namely the resource_providers data table, and keep it consistent with the uuid of the compute_nodes data table in the Nova library through the uuid attribute to achieve a one-to-one correspondence, so as to ensure the consistency of Nova components and Placement components in the computing node, namely the resource_provider resources.

[0059] It should also be pointed out that if the computing node change information in the Nova component and the Placement component is inconsistent, the preset interface of the Placement component is called to create a new computing node resource according to the first universal unique identifier in the Nova component. In other words, since operations such as node name modification and abnormal node delisting and listing may occur in the business environment, the Nova component and the Placement component may be inconsistent. At this time, it is necessary to detect and check the consistency of the above situation. If the computing node information corresponding to the Nova library is not found in the Placement library, it is necessary to call the Placement API to create a new reosurce provider and keep it consistent with the uuid recorded in the compute_nodes database table in the current Nova library. At the same time, the virtual machine data of the computing node inventory before the modification, because it is recorded in the previous resource_provders data, also needs to be updated through the allocations detection system.

[0060] Step S22: If the computing node change information in the Nova component and the Placement component is consistent, run the virtual machine on the computing node of the preset cloud computing management platform, monitor the virtual machine information of the virtual machine, and record the virtual machine information to the Nova component and the Placement component.

[0061] Step S23: determine whether the virtual machine information in the Nova component is consistent with that in the Placement component, and synchronize the virtual machine information in the Nova component to the Placement component according to the determination result.

[0062] In this embodiment, Figure 4 As shown, the first virtual machine information of the target virtual machine in the third data table of the Nova component can be called, and the information acquisition interface of the Placement component can be called to obtain the second virtual machine information in the Placement component to determine whether the first virtual machine information and the second virtual machine information are consistent; wherein the above-mentioned target virtual machine is a virtual machine whose current state is the running state. It can be understood that when the virtual machine is successfully started on the computing node, the instances data table of the Nova library will record the node information where the virtual machine is located, and the compute_nodes data table will update the cpu, memory, disk usage, cpu, memory, disk remaining, the number of virtual machines running on the computing node and other resource-related data. On the other hand, the Placement database will record the resource usage related to the virtual machine through the allocations data table, including consumer_uuid, i.e. virtual machine uuid, resource_class, i.e. resource type (mainly including CPU, memory, disk, GPU card, etc.), resource_provider_id, i.e. node information where the virtual machine is located, and the usage of each resource_class, and it can be understood that in theory, the virtual machine node information and resource usage recorded by the Nova database should be consistent with the Placement database. By calling the Nova database to obtain the Instance (virtual machine basic information uuid, project, user, etc.), Flaver (virtual machine specification information), and PCIdevice (PCI device information) of all active virtual machines in the cluster, a standard data source can be obtained, and the virtual machine uuid, node uuid, virtual machine specifications (CPU, memory, disk allocation), and mounted PCI device status (GPU card) can be extracted from the above data. At the same time, the Placement interface is called to obtain the allocations information of each virtual machine, and a comparative test can be performed to analyze which of the above data has anomalies.

[0063] Accordingly, when synchronizing the virtual machine information in the Nova component to the Placement component according to the judgment result, if there is first virtual machine information in the Nova component that does not correspond to the second virtual machine information in the Placement component, new virtual machine information is created in the Placement component according to the first virtual machine information; if the first virtual machine information and the second virtual machine information corresponding to the same virtual machine in the Nova component and the Placement component are inconsistent, the corresponding second virtual machine information in the Placement component is updated according to the first virtual machine information; if the same virtual machine corresponds to one first virtual machine information and multiple second virtual machine information in the Nova component and the Placement component respectively, the target virtual machine information is filtered out from the multiple second virtual machine information, and the other second virtual machine information is deleted. In other words, if Figure 4 As shown, for a virtual machine that exists in the Nova database but the allocation is not obtained in Placement, it is necessary to call the Placement create allocation API to pass in the standard virtual machine specifications, node information, project, user information, and PCI device information in Nova to create a new allocation; for a virtual machine that exists in the Nova database but the allocation obtained in Placement is incorrect, it is necessary to call the Placement update allocation API to update the incorrect data; for a virtual machine that exists in the Nova database but there may be multiple allocations in Placement, it is necessary to extend the PlacementAPI and delete the redundant allocation data. After the above repairs, the data synchronization of virtual machine resource information in the Nova and Placement databases is finally achieved.

[0064] For a more specific processing procedure of the above step S22, reference may be made to the corresponding contents disclosed in the above embodiments, which will not be described in detail here.

[0065] Through the above technical solution, this embodiment can check the consistency of the resource_provders related data of the computing nodes in the Nova and Placement databases through the resource_provders detection module, and synchronize the computing node related information in the Nova database to the resource_provders data table of the Placement database, and then check the consistency of the virtual machine allocation related data in the Nova and Placement databases through the allocations detection module, and synchronize the virtual machine resource data in the Nova database to the Placement database. In this way, the computing node information recorded in the compute_nodes data table in the Nova database is compared with the information in the resource_providers data table in the Placement database to detect the consistency of the node information, and the missing, redundancy, and error of the resource_providers data in the Placement database are repaired. In addition, the basic information of the virtual machine, the specification data of the virtual machine, and the PCI device information of the virtual machine recorded in the instances, flavors, and pci_devices data in the Nova database are compared with the information in the allocations data table in the Placement database to detect whether the above data are consistent. The missing, redundancy, and error of the resource usage data of the virtual machine project, user, node, CPU, memory, disk, etc. in the allocations data in the Placement database can be repaired, thereby avoiding the abnormality of the virtual machine scheduling function due to the inconsistency of the Nova and Placement virtual machine resource data, and the use of wrong data for analysis and scheduling, and avoiding the abnormality of the node resource monitoring data due to the inconsistency of the Nova and Placement virtual machine resource data, and reporting of the wrong node CPU, memory, disk, PCI device usage and remaining amount.

[0066] See also Figure 5 As shown, the embodiment of the present application also discloses a virtual machine information synchronization device, which is applied to a preset cloud computing management platform, including:

[0069] A data monitoring module 13 is used to run the virtual machine on the computing node of the preset cloud computing management platform if the computing node change information in the Nova component and the Placement component is consistent, monitor the virtual machine information of the virtual machine, and record the virtual machine information to the Nova component and the Placement component;

[0070] The data synchronization module 14 is used to determine whether the virtual machine information in the Nova component is consistent with that in the Placement component, and synchronize the virtual machine information in the Nova component to the Placement component according to the determination result.

[0071] This embodiment can create a virtual machine information synchronization task for a preset cloud computing management platform, and start the virtual machine information synchronization task according to a preset resource information synchronization period, and execute the virtual machine information synchronization task by monitoring the computing node change information of the preset cloud computing management platform. According to the computing node change information, the Nova component and the Placement component of the preset cloud computing management platform are detected, and it is determined whether the corresponding computing node change information in the Nova component and the Placement component are consistent; if the computing node change information in the Nova component and the Placement component are consistent, the virtual machine on the computing node of the preset cloud computing management platform is run, and the virtual machine information of the virtual machine is monitored, and the virtual machine information is recorded in the Nova component and the Placement component; and it is determined whether the virtual machine information in the Nova component and the Placement component is consistent, and according to the determination result, the virtual machine information in the Nova component is synchronized to the Placement component. Through the above technical solution, this embodiment aims at the problem that both the Nova component and the Placement component in the cloud management platform based on OpenStack record the virtual machine resource information, which leads to the risk of inconsistency in the recorded information in the Nova component and the Placement component. By configuring periodic tasks, regular detection and synchronization of the resource information recorded in Nova to the Placement component are performed, the existing function of the OpenStack Nova component is expanded to realize the synchronization of virtual machine resource information, and the virtual machine resource related information in the Nova component of the cloud platform is ensured to correspond one-to-one with the corresponding data in the Placement component, thereby ensuring the consistency of the underlying data and improving the stability of the cloud platform scheduling, monitoring and other functions.
