Abstract

Provided is a virtual machine migration method for migrating a virtual machine from a source physical machine applying a first virtual software to a destination physical machine applying a second virtual software, the method comprising: transferring an image file and a basic profile of the virtual machine from the source physical machine to the destination physical machine, the basic profile being a part common to a profile of the first virtual software and a profile of the second virtual software; at the destination physical machine, combining the basic profile with an extended profile in the destination physical machine to obtain a profile of the second virtual software; and creating a virtual machine on the destination physical machine according to the image file and the profile of the second virtual software.

Description

technical field [0001] The present invention relates to virtual machine technology, and in particular to a virtual machine migration method. Background technique [0002] Cloud computing is a new type of networked computing model based on virtualization technology, with a pay-as-you-go business model, and features such as elastic expansion, dynamic allocation, and resource sharing. In terms of computing resource virtualization, it mainly uses virtualization software to virtualize physical servers into several virtual machines for users to use. Virtualization software is also called hypervisor. Under the x86 architecture, the two mainstream open source virtualization technologies are Xen and KVM. Xen is a virtualization open source project. Xen can safely execute multiple virtual machines on a set of physical machine hardware. It is closely integrated with the operating system platform and occupies few resources. KVM is the abbreviation of Kernel-based Virtual Machine. It i...
