Problems solved by technology

However, for cross-platform virtual machine migration, it is difficult to implement because the underlying implementation technologies may be different
The original open source cross-platform virtual machine migration tool, for example, virt-v2v can realize the migration of other virtual machine platforms to the KVM-based libvirt management platform, but it cannot support other KVM-based management platforms well. After migrating to the libvirt management platform You can only manually import the target management platform from the libvirt management platform, which limits its use

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] as attached figure 1 As shown, a virtual machine migration method based on a plug-in mechanism of the present invention includes a source virtual machine management platform and a target virtual machine management platform, and designs a migration agent module, a driver module, and an import agent module. Based on the above three modules, the virtual The specific migration process of the machine is as follows:

[0036] First, the migration agent module obtains the virtual machine disk image and configuration specification parameters from the source virtual machine management platform, and completes the conversion of the virtual machine image format at the same time;

[0037] Then the driver module is used to manage the driver plug-ins of the source virtual machine management platform and the destination virtual machine management platfo...

Abstract

The invention discloses a plug-in mechanism-based virtual machine migration method. According to the plug-in mechanism-based virtual machine migration method, a source virtual machine management platform and a target virtual machine management platform are provided, and a migration agent module, a driving module and an import guide module are designed. Based on the three modules, the particular migration process of the virtual machine is as follows: the migration agent module acquires a virtual machine disk image and a configuration specification parameter of the virtual machine from the source virtual machine management platform and finishes conversion; the driving module is used for managing and driving a plug-in; the import agent module rebuilds a virtual machine on the target virtual machine management platform by using the converted virtual machine disk image. Compared with the prior art, the plug-in mechanism-based virtual machine migration method has the advantages that automatic migration of the cross-platform virtual machine is realized; the virtual machine migration efficiency in the operating and maintaining process of the virtual machine management platform is effectively improved; the method is based on an extensible design architecture, so that the new virtual machine management platform can be supported without modifying the original system, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of virtualized cloud computing, in particular to a highly practical virtual machine migration method based on a plug-in mechanism. Background technique [0002] With the maturity of virtualization technology, many mature commercial and open source virtualization technologies have emerged, among which the commercial version is represented by VMware, which is mature and stable. However, open source virtualization technologies such as KVM and Xen have also developed rapidly, becoming increasingly mature and stable in terms of functions and performance. On this basis, the development of cloud computing is surging, and major manufacturers have invested funds and technical strength to develop their own cloud products. [0003] However, the underlying products of different vendors may use different virtualization technologies, which leads to a new demand for V2V (Virtual-to-Virtual) migration of virtual machines. ...
