Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0031] First build a virtual machine resource monitoring and scheduling system in the hybrid cloud to realize real-time monitoring of virtual machine resources including memory, CPU, disk, and network bandwidth. The system framework diagram is as follows figure 2 shown. It includes a monitoring and scheduling module for resources in the virtual machine. On the whole, it is divided into three basic stages: data collection, data extraction and execution scheduling. There are several physical machine cl...

Abstract

The invention provides a scheduling method and system for virtual-machine memory self-adaption thermal migration in a hybrid cloud mode. The method includes the steps that a dirty-page-rate prediction model is established and used for predicting the current dirty page rate of a source virtual machine memory after iteration copying is carried out; the source virtual machine memory is subjected to iteration copying one time, and the current dirty page rate is compared with a current-dirty-page-rate threshold value, whether the continuous iteration copying step is carried out or stopping copying and copying as required are carried out is determined; the source virtual machine memory is subjected to continuous iteration copying, and according to the time number of continuous iteration copying or comparison of the current dirty page rate and the current-dirty-page-rate threshold value, and whether stopping copying is carried out or not is determined, wherein the current-dirty-page-rate threshold value is equal to the average value of the current dirty page rates of all applications in the source virtual machine memory. By means of the scheduling method and system for virtual-machine memory self-adaption thermal migration in the hybrid cloud mode, whole migration time can be effectively shortened, the total memory-data migration amount is greatly reduced, and meanwhile self-adaption virtual-machine resources in different application scenes are scheduled.

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...
