Abstract

The present invention provides a virtual machine memory self-adaptive hot migration scheduling method and system in a hybrid cloud mode, comprising: constructing a dirty page rate prediction model to predict the current dirty page rate after iterative copying in the source virtual machine; Perform an iterative copy of the virtual machine memory. By comparing the current dirty page rate with the current dirty page rate threshold, it is decided whether to continue the iterative copy step or to perform shutdown copy and on-demand copy; to continue iterative copying of the source virtual machine memory, according to the continuous iterative copy The number of times, or according to the comparison between the current dirty page rate and the current dirty page rate threshold, decide whether to enter the shutdown copy; wherein, the current dirty page rate threshold is equal to the average value of the current dirty page rate of all applications in the source virtual machine memory. The present invention can effectively reduce the overall migration time and greatly reduce the amount of total memory data migration; at the same time, it is aimed at the self-adaptive virtual machine resource scheduling in different application scenarios.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular to a method for adaptive hot migration scheduling of virtual machine memory resources in a hybrid cloud mode. Background technique [0002] At present, cloud computing resources are widely used in the commercial field, and more and more enterprises and developers deploy their services and applications on hybrid clouds including private clouds and public clouds. However, due to the limitation of virtual machine resources and the consideration of load balancing among virtual machines, enterprises and developers must perform live migration of virtual machines according to their needs. Virtual machine live migration, also known as live migration (hot migration), is a process of migrating virtual machine resources from a source host to a destination host on the premise of ensuring uninterrupted services in the virtual machine. In order to ensure that the virtual mach...
