Virtual machine switching system and method

Abstract

The invention provides a virtual machine switching system. The virtual machine switching system is used for switching virtual machines when one virtual machine is abnormal, and comprises a base image setting module, a virtual machine generating module and an automatic switching module. The base image setting module is used for correspondingly setting and storing at least one virtual machine base image according to at least one virtual machine, and the virtual machine generating module is used for generating and starting the corresponding new virtual machine according to virtual machine information and virtual machine image information corresponding to the virtual machine when the virtual machine is abnormal. The automatic switching module is used for achieving switching between the new virtual machine and the corresponding abnormal virtual machine so that the new virtual machine can replace the abnormal virtual machine to work normally. The switching system achieves automatic switching between the new generated virtual machine and the abnormal virtual machine when the virtual machine works abnormally so that the new virtual machine can replace the abnormal virtual machine to work normally, operation is convenient, and continuity of services provided by the virtual machine can be guaranteed. The invention further provides an automatic virtual machine switching method.

Description

technical field [0001] The invention relates to virtualization technology, in particular to a virtual machine switching system and switching method. Background technique [0002] At present, server virtualization technology virtualizes a physical server into multiple isolated virtual servers. Each virtual server has independent CPU, memory, disk space and network bandwidth, which improves resource utilization efficiency and simplifies system management. During the use of virtualization technology, the security of network information needs to be guaranteed for the normal use of virtualization technology. Traditional network security protection uses intrusion detection, firewall technology, etc. to protect the system from network attacks. [0003] However, due to various internal and external unstable factors encountered when the system is running, traditional security protection technologies require manual intervention to restore the system when the virtual server is abnormal...

AI Technical Summary

Problems solved by technology

[0003] However, due to various internal and external unstable factors encountered when the system is running, traditional security protection technologies require manual intervention to restore the system when the virtual server is abnormal, such as being attacked by a Trojan horse or a virus, which is inconvenient to operate. At the same time affect the normal work of the virtual server
