Abstract

The invention discloses a virtual machine migration method, which is used for migrating a virtual machine from a source physical machine using first virtualization software to a target physical machine using second virtualization software. The method comprises the following steps of transmitting a mirror image file and a basic configuration file of the virtual machine from the source physical machine to the target physical machine, wherein the basic configuration file is a common part of a configuration file of the first virtualization software and a configuration file of the second virtualization software; combining the basic configuration file with an expansion configuration file in the target physical machine in the position of the target physical machine to obtain a configuration file of the second virtualization software; and creating the virtual machine on the target physical machine according to the mirror image file and the configuration file of the second virtualization 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-basedVirtualMachine. It is ...
