Problems solved by technology
However, the COLO technology determines whether checkpoint is required, and it completely depends on the comparison result of the response packet generated by the active and standby virtual machines to the client's network request, resulting in an unnecessary waste of the calculation of the standby virtual machine after obtaining the random number.

The invention provides a virtual machine fault-tolerant system and a fault-tolerant method thereof, which are used for carrying out state data synchronization on main and standby virtual machines after a main virtual machine generates a random number, and the virtual machine fault-tolerant system comprises a main virtual machine monitor and a standby virtual machine monitor. A main virtual machineis installed on the main virtual machine monitor, and a standby virtual machine is installed on the standby virtual machine monitor. After the main virtual machine generates a random number, the mainvirtual machine monitor sends an instruction of state data synchronization between the main virtual machine and the standby virtual machine to the main virtual machine, so that the main virtual machine synchronizes the state data of the main virtual machine to the standby virtual machine. Therefore, inconsistency of the state data of the main virtual machine and the standby virtual machine is found as soon as possible, the main virtual machine monitor initiates state data synchronization of the main virtual machine and the standby virtual machine actively, state data synchronization of the main virtual machine and the standby virtual machine is carried out timely, and calculation expenditure caused by random number generation, network response data packet generation and network response data packet comparison of the main virtual machine and the standby virtual machine is avoided. Therefore, waste of computing resources of the standby virtual machine is avoided.
Description
technical field [0001] The invention relates to the technical field of virtual machines, in particular to a virtual machine fault-tolerant system and a fault-tolerant method thereof. Background technique [0002] With the development of cloud computing, virtualization technology has been widely used, and virtual machine fault tolerance technology can provide reliability guarantee for key applications. In the early virtual machine fault-tolerant technologies (such as MicroCheckpointing, Kemari, etc.), the standby virtual machine was always in a suspended state, and the state changes of the primary virtual machine were synchronized frequently at high frequency. If the primary virtual machine failed, the standby virtual machine was activated to run. Periodic high-frequency Checkpoint (checkpoint mechanism, a state data synchronization method) is performed between the active virtual machine and the standby virtual machine. At the same time, Checkpoint needs to suspend the runnin...
