Problems solved by technology

[0004] Existing high-availability technologies for virtual machines improve the availability of application services provided by virtual servers to a certain extent. If the process that provides application services to the outside world fails, for example, the process is accidentally killed, the process does not respond, etc., then the virtual machine high availability technology is also helpless

Abstract

The invention discloses a virtual machine application service failure recovery system and method. The system comprises a virtual machine managing module, a virtual hardware watchdog module, a watchdog driving module and a watchdog multiplex module. The virtual machine application service failure recovery system registers application service into the watchdog multiplex module which carries out monitoring on the registered application service. When the watchdog multiplex module monitors the fact that the application service is in fault and in-fault time is longer than the overtime set by the virtual hardware watchdog module, the virtual machine managing module triggers overtime operation set by the virtual hardware watchdog module. The service usability set by a virtual server is further improved so that when an operation system is in fault or an application service process is in fault, the virtual server can recover from the fault quickly and provide service for external sides continuously.

Description

technical field [0001] The invention relates to the technical field of virtualization, in particular to a virtual machine application service fault recovery system and a fault recovery method thereof. Background technique [0002] At present, with the continuous development of computer hardware technology, powerful hardware capabilities make it easy to run multiple independent application platforms on a single computer, and server integration can improve resource utilization and save hardware costs. With these advantages, virtualization technology is more and more widely used in the field of server consolidation, and many large and small servers in virtualized environments have been built in different industries. [0003] The benefits of using a virtual machine as a server are obvious, but the availability of application services provided by using a virtual machine as a server limits the application of virtual servers. Because multiple virtual machines exist on the same phy...
