Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0043] see figure 1 As shown, the embodiment of the present application discloses a virtual machine high availability method, including:

[0044] Step S11 : when it is monitored that a node in the cluster is faulty, a virtual machine evacuation request for each faulty node is generated.

[0045] In a specific implementation, when a node in the cluster is monitored to fail, a virtual machine evacuation request for each failed node is generated, and the current failed node can be iso...

Abstract

The invention discloses a virtual machine high availability method, device and equipment, and the method comprises the steps: generating a virtual machine evacuation request for each fault node when afault of a node in a cluster is monitored; determining resource requirements corresponding to the virtual machine evacuation requests one by one; judging whether the available resources in the cluster meet the resource demand corresponding to the current virtual machine evacuation request or not: if so, determining a target migration node corresponding to the current virtual machine evacuation request and a corresponding resource to be used according to the resource demand, migrating the virtual machine on the corresponding fault node to the target migration node, and then performing a corresponding virtual machine recovery operation on the target migration node, or else, fusing the virtual machine evacuation request. Thus, the situation that resource competition is generated when the virtual machines on the fault nodes are evacuated can be avoided, the evacuation request is fused in time when available resources in the cluster are insufficient, and therefore, the stability of the system is guaranteed.

Description

technical field [0001] The present application relates to the technical field of cloud computing, and in particular to a high-availability method, device and equipment for a virtual machine. Background technique [0002] Virtualization is a physical model that can make full use of physical resources and share computing resources through the Internet. It can provide on-demand resources and services, and dynamically allocate resources. As virtualization continues to develop, virtual machines are the central point of technology implementation. How to ensure that in the event of a node failure in the local system, the virtual machines running on it can be evacuated to run on other healthy nodes to ensure that the virtual machines can Continue to accept the management of this system and realize the high availability of virtual machines is a huge challenge for the current virtualization technology. The current high-availability solutions for virtual machines are usually implemen...
