Problems solved by technology

Since the new master node is elected by all the slave nodes according to the election algorithm after the failure occurs, the recovery time is relatively long
[0008] In addition, the snapshot technology (snapshot), if the backup data needs to be changed before the set restore point and a failure occurs, the system will be difficult to restore to the state before the failure occurred
[0009] To sum up, the shortcomings of lack of flexibility and long fault recovery time in the above-mentioned methods

Embodiment Construction

[0071] The role-based virtual machine pool high-availability guarantee technology and system of the present invention can effectively solve the single-point failure problem through fault detection and fault recovery of master and backup nodes. The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0072] In the high-availability module of the system, the role-based dual-machine hot backup processing method is used to ensure that when the master node in the resource pool goes down, an effective backup node takes over its work to ensure that the system can provide services normally. The following It is explained based on specific scene examples.

[0073] 1. The process of role-based dual-machine hot standby, such as image 3 shown.

[0074] On the basis of the definition of triplet in section 3.1, change the third element to indicate whether the node is valid (invalid means invalid, valid means valid), assu...

Abstract

The invention relates to a high-availability virtual machine pooling management system based on roles. According to the virtual machine pooling management method, a master node, a slave node and a backup node are included. The master node is the only logic entrance of a virtual machine resource pool and responsible for managing all nodes in the resource pool. The slave node is mainly responsible for managing a life cycle of a virtual machine of the slave node. The backup node is used for backing up state information of the master node, ensuring consistency with the state information of the master node, and taking over the work of the master node when the master node fails. During a virtual machine pooling management process, all the nodes can switch over three roles along with different conditions, wherein the three roles are the master node, the slave node and the backup node. A serial method is used for ensuring that only one master node and one backup node exist in the system and a double-direction asynchronous communication mechanism is used for ensuring consistency of data of the master node and the backup node. The high-availability virtual machine pooling management system based on the roles improves reliability of a virtualized system and flexibility of management.

Description

technical field [0001] The present invention relates to a role-based high-availability virtual machine pool management system. The system expands the traditional failover cluster high-availability guarantee technology and is used to solve the problem of long recovery time and failure caused by single-point failure of virtual machine pool management. Managing complex problems belongs to the field of software technology. Background technique [0002] A virtual machine can provide a virtual computer system for operating systems and applications, and the operating environment it constructs can run a complete operating system and is completely transparent to upper-layer applications. Virtual machine pool management refers to a virtualization technology that provides virtual machine life cycle management and resource on-demand provision from a unified management perspective. In recent years, virtual machine pool management has become one of the key technologies for building mains...
