Embodiment Construction

[0026] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0027] The schematic diagram of the structure of the present invention is attached figure 1 As shown, the core module of the whole system is the synchronization engine. The synchronization engine is divided into three parts: through heartbeat monitoring to check whether the primary virtual machine is faulty; through live migration to realize memory synchronization; through mirrored snapshots to realize the synchronization of the storage mirrors of the primary and backup machines.

[0028] First, the heartbeat monitoring of the synchronization engine is introduced: as the virtual machine runs, when its content is modified to a certain extent, the data will be written back to the disk image. The heartbeat monitoring module is responsible for monitoring the disk data writeback of the primary virtual machine. Once it is found that the disk writeback is delayed or...

Abstract

The invention provides a method for improving availability of a virtual machine system based on thermomigration. The method comprises the following steps: firstly, before a main virtual machine is started, a main virtual machine image file on a source server is copied onto a backup server and then the virtual machine system is started; the system can start a source virtual machine to operate on a master server; a backup virtual machine is switched to a suspension state on a backup server and a synchronous engine is started in the background to carry out heartbeat monitoring, high-frequency thermomigration and synchronization of image files; and once the crash of the virtual machine on the master server is found, the backup virtual machine on the backup server is recovered to an operation state from the suspension state immediately so as to provide service outwards, therefore the high availability of the virtual machine is realized.

Description

technical field [0001] The invention relates to the technical field of computer virtual machines, in particular to a method for improving the availability of a virtual machine system based on hot migration. Background technique [0002] With the rapid development of computer and network technology, especially the emergence of multi-core processors, the performance of physical machines has been rapidly improved, but traditional usage methods often fail to make full use of the capabilities of physical machines, so virtualization technology has emerged, which can be used in Running multiple virtual computer systems (referred to as virtual machines) on a single physical machine greatly improves the utilization of the physical machine. In addition, virtualization technology is used to realize the packaging of software, which can shield the influence of heterogeneous hardware on software, and multiple virtual machines running on the same physical machine can run independently of e...
