Embodiment Construction

[0030] 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, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] In a virtualized cluster system, there are multiple physical nodes, including management nodes with management functions and physical nodes without functional physical nodes). Each physical node includes a virtual machine monitor, through which multiple virtual machines can run; each physical node also includes a local scheduler, which is used to implement a local scheduling strategy, that is, the CPU and memory in the physical node Do dynamic allocation. ...

Abstract

The embodiment of the invention discloses a method, a device and a system for balancing loads of virtual cluster systems, wherein the method comprises the following steps: acquiring load information of a virtual machine in physical nodes in a virtual cluster system, wherein the load information comprises the CPU utilization rate of the virtual machine and the use magnitude of memory; obtaining first load information in a first moment according to the load information and adjusting the CPU utilization rate of the virtual machine in the physical nodes and the use magnitude of memory according to the first load information; and obtaining second load information in a second moment according to the load information and adjusting the migration of the virtual machine among the physical nodes in the virtual cluster system according to the second load information. Due to the embodiment of the invention, the load balance of the virtual cluster system can be realized, and the overhead needed for realizing the load balance is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a load balancing method, device and system of a virtualized cluster system. Background technique [0002] System-level virtualization is to add a virtual machine monitor (VMM, Virtual Machine Monitor) between the computer hardware and the operating system to remove the direct dependency between the computer hardware and the computer operating system. The virtual machine monitor here is a computer Hardware platform virtualization software, through the virtual machine monitor, can run multiple virtual machine instances on the same computer, each virtual machine has a corresponding machine name, an independent virtual network address, and the user on each virtual machine Management is independent of each other and uses a portion of the allocated device resources. A hardware device with independent computing and storage capabilities (such as a computer including har...
