Scheduling method and scheduling system of nova component virtual machine based on openstack

Abstract

The invention belongs to the technical field of communications, and in particular relates to a scheduling method and a scheduling system for a Nova component virtual machine based on openstack. The scheduling method includes the steps of: receiving instance information of a virtual machine to be migrated; obtaining and summarizing information of each computing node, establishing a Nova component virtual machine scheduling live migration model; according to the Nova component virtual machine optimization scheduling evaluation function, calculating the information vector of the computing node, Obtain the scheduling result that satisfies the Nova component virtual machine optimization scheduling evaluation function; execute the scheduling result, and assign the Nova component virtual machine to the computing node with the optimal scheduling evaluation function value; it includes the load rate Ρ to the computing node, the free storage space value M 1. Dynamic iterative calculation of virtual machine failure rate λ; before obtaining the scheduling result that satisfies the optimal scheduling evaluation function of the Nova component virtual machine, repeat the steps of obtaining and summarizing the information of each computing node and the step of calculating the information vector of each computing node. Solved the problems of high virtual machine congestion and system instability.
