Problems solved by technology

[0004] Due to the different hardware configurations of different physical hosts, especially the different number of CPUs and cores, the virtual machine needs to be unbound from the original bound host during migration, but sometimes the configuration file in the virtual machine cannot Immediate update, resulting in the failure of cross-host migration of virtual machines, which seriously limits the application scenarios and practicability of virtual machines

Abstract

The invention discloses a virtual machine migration method and device. The virtual machine migration method includes the steps that firstly, the length of a vcpu bound byte of the virtual machine to be migrated is compared with that of each CPU byte of a current host to determine the binding condition of a vcpu; when the length of the vcpu bound byte is the same as that of the cpu byte, vcpu bit diagrams and corresponding cpu bit diagrams are computed bit by bit; when the computed result is 1 and the quantity of bound vcpu is 1, a total number is set to be 0, and the data structures of vcpu bound bits are set to be blank; when the total number is not 1, the data structure of each vcpu bound bit is processed sequentially according to a predetermined algorithm; finally, the data structures of the vcpu bound bits stored in an XML of the virtual machine and the total number of the bound vcpu are updated. The success rate of virtual machine migration is increased, migration restriction is reduced, and the virtual machine migration method and deviceareconducive to adding the usage scenes of a virtual machine migration function.

Description

technical field [0001] Embodiments of the present invention relate to the fields of virtualization and cloud computing, and in particular, to a virtual machine migration method and device. Background technique [0002] Driven by the wave of cloud computing technology, virtualization technology continues to develop. Virtualization is a resource management technology that abstracts and converts various physical resources of a computer, such as servers, networks, memory, and storage, and presents them after conversion, breaking the inseparable barriers between physical structures, so that users can compare with the original A better way to apply these resources, according to different needs to re-plan to achieve maximum utilization, to achieve automatic deployment of various resources, dynamic expansion, on-demand allocation, and improve the utilization of IT resources. [0003] Virtualization technology has given birth to a virtual machine, that is, a complete computer system...
