Virtual cluster management system and cluster node

Abstract

The embodiment of the invention discloses a cluster node applied to virtual cluster management, which comprises a cluster node management module, a middleware interface, a virtual machine monitor set and a virtual machine, wherein the cluster node management module is used for a user-side call management command transmitted by a cluster management node and judges the type of the call management command; the middleware interface is used for providing an interface which corresponds to the call management command for the cluster node management module so as to call virtual machine monitors in the virtual machine monitor set when the call management command is the monitoring call management command of the virtual machine monitors; and the virtual machine monitor set is used for monitoring and managing the virtual machine which is in communication linkage with the virtual machine monitors. The embodiment of the invention also provides a virtual cluster management method. Various interfaces are provided for an upper level by the middleware interface so that the upper level does not need to modify and manage different types of virtual machine monitors, thereby improving the efficiency of virtual cluster management.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a virtualized cluster management method and cluster nodes. Background technique [0002] In the early days of virtualization technology, it mainly virtualized expensive host systems into multiple independent virtual machines. System-level virtualization adds a virtual machine monitor (VMM, Virtual Machine Monitor) between the computer hardware and the operating system to remove the direct dependence between the two. With the improvement of the performance of general-purpose processors including x86 architecture processors, coupled with the characteristics of virtualization technology that can effectively reduce costs, easy management, improve system availability, dynamic load balancing, and strengthen security policies, microprocessor computing systems Virtualization technology has become a new trend in technology. [0003] Through the vir...

Problems solved by technology

[0005] In the process of implementing the present invention, the inventor found that the prior art has at least the following disadvantages: the prior art regards virtual nodes as physical nodes and adopts a flat structure for management. Since physical nodes are entities with independent functions constituting a cluster, and A virtual machine is a virtual machine virtualized through virtualization technology on the basis of physical nodes, that is, the difference between virtual nodes and physical nodes is not considered, resulting in low efficiency in managing virtual machine nodes by using physical nodes to manage nodes
