Abstract

The embodiment of the invention provides a method, a device and a system for transferring from a physical machine to a virtual machine on line. The method comprises the following steps: after building, starting and hanging a target virtual machine on a virtualization platform virtual machine manager (VMM) Host, initially synchronizing memory page data to a target virtual machine from the original physical machine at the second time point; from the second time point, monitoring the memory page updating operation; incrementally synchronizing the updated memory page data in the original physical machine to the target virtual machine; stopping monitoring until the updated increment value in the memory page of the original physical machine is less than a first threshold value; calling the virtualization platform VMM Host to restore the target virtual machine to the operation state; building a target virtual machine having the basically same operation state with the original physical machine so as to realize the state that the target virtual machine continues operating by following the state of the original physical machine, thus avoiding the problem of service interruption, and realizing the effect on smoothing switching service from the original physical machine to the target virtual machine.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, device and system for online migration from a physical machine to a virtual machine. Background technique [0002] With the maturity of virtualization technology, the performance of hardware devices is now improved, and the original devices are damaged or aging. More users are more willing to use virtualization technology to migrate the system on the old device to new hardware, saving maintenance and energy consumption costs. Reduced footprint. During the migration process, a P2V (Physical Machine to Virtual Machine, physical machine to virtual machine migration) tool is required. [0003] P2V tools are used to quickly and cleanly migrate systems and applications on existing physical hosts to virtual hosts, eliminating the need to reinstall software and configure complex application environments, and shorten the time for deployment and application ...
