Cloud computing virtual machine placement method based on resource use curve complementation

Abstract

The invention discloses a cloud computing virtual machine placement method based on resource use curve complementation. A main idea is characterized by picking out an overload physical host, selectinga virtual machine on the overload physical machine; predicting the resource use condition of the system at t time points in the future; predicting the resource use condition of the physical host formigration at t time points in the future; and searching a physical host to enable the resource use condition of the physical host to be complementary to the resource use condition of the virtual machine; calculating the complementation degree between the physical host and the virtual machine, calculating the complementation degree between all the virtual machines on the overloaded physical host and all the migration-available physical hosts according to the process, selecting a group of virtual machines and physical hosts with the maximum complementation degree values, and migrating the virtual machines to the physical host, and if the physical machine is still overloaded after migration, removing the corresponding comprehensive complementarity from the comprehensive complementarity set and reselecting a group of virtual machines to migrate with the physical host until the physical machine is not overloaded or the comprehensive complementarity set is empty.

Description

technical field [0001] The invention belongs to the field of cloud computing and virtualization, and specifically relates to a cloud computing virtual machine placement method based on complementary resource usage curves, which is mainly used to reduce the number of virtual machine migrations and improve the utilization rate of physical machine CPU resources, so as to reduce the cost of the entire data center. energy consumption. Background technique [0002] Cloud computing is a new technology that provides services to users on demand, and it has a revolutionary impact on the information technology industry. The development of cloud computing has spawned thousands of data nodes. Virtualization technology is a key technology of cloud computing. It is the basis for cloud computing to provide on-demand services. In a virtualized environment, hardware resources can be allocated according to requirements. From the perspective of the data center, virtualization technology enab...

Problems solved by technology

At present, most of the migration methods are only based on whether the physical machine is overloaded or not, and do not conduct a specific analysis of the resources of the virtual machine and the physical machine, which directly leads to the short effective time of the migration and the waste of a large amount of physical machine resources.
