Abstract

The invention discloses a virtual machine migration method and a virtual machine migration system, relates to the field of cloud calculation and solves problems the an existing virtual machine resource scheduling mechanism is unable to satisfy variability of actual operation status of the system and low in efficiency. The method includes: determining virtual machine filling priority of host equipment in a cluster; migrating at least one virtual machine on the host equipment low in virtual machine filling priority to the host equipment with the load not up to the limit and high in the virtual machine filling priority. The virtual machine migration method and the virtual machine migration system are applicable to the large-scale virtual machine cluster, and dynamic adjustment of virtual machine resource scheduling is realized.

Description

technical field [0001] The invention relates to cloud computing technology, in particular to a virtual machine migration method and system. Background technique [0002] In the era of cloud computing, as the application fields of cloud services become wider and wider, the scale of server clusters based on virtualization technology is getting larger and larger, which poses new challenges to cluster resource scheduling. In a large-scale virtual machine cluster, the number and load of virtual machines will often change with the requirements of use. Static resource allocation will cause resource waste or resource shortage, while dynamic resource adjustment through manual intervention will cause There is a noticeable hysteresis. [0003] To sum up, the existing virtual machine resource scheduling mechanism cannot adapt to the variability of the actual working conditions of the system, and the efficiency is low. Contents of the invention [0004] In order to solve the above te...
