Problems solved by technology
During live migration of a virtual machine, the generation speed of dirty pages is generally greater than the migration speed, that is, the generation speed of dirty pages is greater than the bandwidth of the network card between the source node and the target node, which will lead to a longer time for virtual machine hot migration

Embodiment Construction
[0034]In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.
[0035]The virtual machine hot migration method provided in this application can be applied tofigure 1 In the application environment shown. The application scenario includes a management terminal 102, a source node 104, and a target node 106. The management terminal 102 is connected to the source node connection 104 through a network, and the source node 104 is connected to the target node 106 through the network. The user can initiate a hot migration request to the source node 104 through the management terminal 102, requesting that the virtual machine of the source node 104 be migrated to the target node 106. After th...

The invention relates to a database synchronization technology, in particular to a virtual machine thermal migration method and device and computer equipment. The method comprises the steps of receiving an access request initiated by a target node, wherein the access request is used for accessing preset dirty page index data, and the access request is generated when the target node responds to a virtual machine thermal migration request; in response to the access request, reading and sending dirty page data corresponding to the index record in the dirty page index data to a target node; when adirty page data writing success message fed back by the target node is received, deleting the read index record in the dirty page index data to obtain dirty page index updating data; and updating thedirty page index data by using the dirty page index updating data, and re-reading and sending the dirty page data corresponding to the index record in the dirty page index data to the target node until the data corresponding to the index record in the dirty page index data is migrated. Through the dirty page indexing mode, the whole memory page does not need to be transmitted, and the thermal migration duration can be shortened.
Description
Technical field[0001]This application relates to the field of computer technology, in particular to a virtual machine hot migration method, device and computer equipment.Background technique[0002]Cloud technology refers to the general term of network technology, information technology, integration technology, management platform technology, application technology, etc. based on the application of cloud computing business models, which can form a resource pool, which can be used on demand, flexible and convenient. The back-end service of the technical network system requires a large amount of computing and storage resources, such as video websites, image websites and more portal websites. With the rapid development and application of the Internet industry, in the future, each item may have its own identification mark, which needs to be transmitted to the background system for logical processing. Data of different levels will be processed separately, and all types of industry data nee...
