Embodiment Construction

[0089] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0090] The method described in the embodiment of the present invention can be applied in such as figure 1 On the cluster management server in the shown cluster system, wherein the cluster management server is responsible for managing each physical host having a communication connection with it, wherein each physical host includes a hardware layer, and the virtual machine running on the hardware layer A monitor VMM, at least one virtual machine ru...

Abstract

The embodiment of the invention provides a virtual machine placement method and a cluster management server. Candidate weighted values of physical main machines are determined according to one-machine resource balance degrees and cluster balance degrees of the physical main machines, and the physical main machines with the maximum candidate weighted values or with the candidate weighted values larger than or equal to a preset value serve as placement physical main machines of a virtual machine. Therefore, when the virtual machine placement is carried out, one-machine resource operation conditions of the physical main machines serve as constraints, and load balancing between different physical main machines in a cluster is further considered. Therefore, the requirements for promoting the use ratio of the physical main machines and reducing migration expenses of the virtual machine are both considered when the virtual machine placement is carried out.

Description

technical field [0001] The invention relates to the field of virtualization clusters, in particular to a virtual machine placement method and a cluster management server. Background technique [0002] The so-called virtual machine placement refers to selecting a suitable physical host (also called a physical server or a physical computing node) for the virtual machine when the virtual machine is started, and placing the virtual machine on the selected physical host. Different placement strategies have different impacts on the performance of virtual machines and the resource utilization of physical hosts. [0003] The existing virtual machine placement methods are either based on the balance of multi-dimensional resources (such as central processing and memory) of a single physical host, or based on the load balance among physical hosts in the cluster, and cannot take into account a single physical host. The multi-dimensional resource balance degree and the load balance degr...
