Problems solved by technology

However, before the Linux virtual machine is migrated, people need to shut down the Linux virtual machine first, and then migrate the Linux virtual machine, which will cause the user to be unable to use the virtual machine provided by the virtual machine normally for a long time during the migration process of the Linux virtual machine. Virtualize services, which can have a huge negative impact on user experience

Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] The embodiment of the present invention discloses a Linux virtual machine migration method, see figure 1 As shown, the method includes:

[0039] Step S11: Copy all memory data on the source virtual machine that is currently online to the target virtual machine that is currently offline.

[0040] In this embodiment, the source virtual machine and the target virtual machine are virtual machines on different virtualization platforms.

[0041] Step S12: M...

Abstract

The invention discloses a Linux virtual machine migration method and system. The Linux virtual machine migration method comprises the following steps of Step S11, copying all memory data on a source virtual machine currently in the online state into a target virtual machine; Step S12, monitoring whether the memory data on the source virtual machine changes or not; if so, entering Step S13; if not, switching the source virtual machine into an offline state and entering Step S16; Step S13, judging whether the memory data difference degree of the source virtual machine and the target virtual machine is smaller than the preset degree or not; if not, entering Step S14; if so, entering Step S15; Step S14, copying dirty memory data generated in the last copying process into the target virtual machine and entering the Step S12; Step S15, switching the operation state of the source virtual machine into the offline state; copying the dirty memory data generated in the last copying process into the target virtual machine; Step S16, switching the target virtual machine into an online state. The machine halt time of the virtual machine can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of virtual machines, in particular to a Linux virtual machine migration method and system. Background technique [0002] At present, with the rapid development of computer virtualization technology, the scope of application of Linux virtual machines continues to expand, and has attracted the attention of banks, governments, military forces, and various large and small enterprises. In the existing virtual machine application process, people often need to migrate the Linux virtual machine from one virtualization platform to another virtualization platform. However, before the Linux virtual machine is migrated, people need to shut down the Linux virtual machine first, and then migrate the Linux virtual machine, which will cause the user to be unable to use the virtual machine provided by the virtual machine normally for a long time during the migration process of the Linux virtual machine. Virtualization servi...
