Abstract

The invention provides a virtual machine migration decision method and device. The method comprises the following steps: acquiring network traffic statistics information of a physical node and network traffic occupation information of virtual machines in the physical node; judging whether the network traffic statistics information of the physical node satisfies threshold information or not, wherein the threshold information is traffic information of the physical node under normal work; if the network traffic statistics information of the physical node does not satisfy the threshold information, determining difference values between the network traffic occupation information and traffic occupation information of the virtual machines respectively according to preset traffic occupation information of the virtual machines; and migrating the virtual machines according to the difference values. Through the technical scheme, the problems that network congestion occurs and a dynamic decision cannot be made due to virtual machine migration in an existing scheme are solved. Whether the virtual machines need to be migrated or not is judged according to the network traffic statistics information of the physical node and the network traffic occupation information of the virtual machines in the physical node; migration of the virtual machines is decided dynamically; and the human participation degree of system maintenance is lowered.

Description

technical field [0001] The invention relates to the fields of cloud computing and network virtualization, in particular to a virtual machine migration decision method and device. Background technique [0002] With the development of cloud computing technology and network virtualization technology, OpenStack provides a set of operating platforms or tool sets for cloud deployment, and provides solutions for cloud computing infrastructure services. OpenStack has the characteristics of open source, interoperability, portability, and ease of use, and also provides developed API (Application Programming Interface, application programming interface) for secondary development, and can be easily integrated with other systems, winning the industry More and more attention. [0003] The migration of a virtual machine refers to moving the virtual machine operating system and applications running on the source physical host to the target physical host, and they can run normally on the ta...
