Openstack-based Nova component virtual machine scheduling method and system

Abstract

The invention, which belongs to the technical field of communication, especially relates to an openstack-based Nova component virtual machine scheduling method and system. The scheduling method comprises the steps of: receiving instance information of a to-be-migrated virtual machine; obtaining and gathering information on each computational node and establishing a scheduling live migration model of a Nova component virtual machine; calculating information vectors of computational nodes according to a Nova component virtual machine optimization scheduling evaluation function to obtain scheduling results meeting the Nova component virtual machine optimization scheduling evaluation function; and carrying out the scheduling results and distributing the Nova component virtual machine to the computational node with the optimal scheduling evaluation function value, wherein the specific operations include: carrying out dynamic iterative computation on load factor P, free storage space value M and virtual machine operation fault rate lambda of the computational nodes, and repeating the step of obtaining and gathering information on each computational node and the step of calculating information vectors of computational nodes before the scheduling results meeting the Nova component virtual machine optimization scheduling evaluation function are obtained. The invention solves the problem of high operation congestion degree and unstable system of the virtual machine.
