Abstract

The embodiment of the invention provides a method and system for dispatching a virtual machine. The method comprises the steps as follows: analyzing a running log of a virtual machine cluster in an offline state to obtain running characteristics of virtual machine operations in the virtual machine cluster; fitting according to the running characteristics of the virtual machine operations to obtain a characteristic curve of the load related parameters of the virtual machine; dividing a running cycle of the virtual machine into a plurality of initial stages according to the characteristic curve and carrying out resource demand calculation on the divided initial stages in the characteristic curve to obtain a first histogram; carrying out optimal adjustment of local resource distribution on the first histogram by calling a dynamic programming algorithm to obtain a second histogram and carrying out final stage division according to the second histogram; and solving a stage division graph model according to the second histogram and determining a virtual machine migration path by solving the stage division graph model. According to the invention, the energy-saving pertinence is achieved and the energy-saving effect can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of virtual machines, and more specifically, to a virtual machine scheduling method and system. Background technique [0002] With the development of virtualization technology, virtualization technology has been widely used in data centers. Data centers can virtualize multiple isolated virtual machines (Virtual Machines, VMs) on one physical host through virtualization technology. A virtual machine can run mutually independent operating systems at the same time, and these guest operating systems (guest OS) access actual hardware resources through a virtual machine manager (Virtual Machine Manager, VMM). Through the application of virtualization technology, the data center can cope with the increasing demand for data processing. [0003] However, with the rapid growth of data center scale, the power consumption brought by it has become one of the key problems that must be solved. At present, data cen...
