Abstract

The present invention discloses a server integration oriented high efficiency physical machine to virtual machine (P2V) conversion method. The method can minimize a failure time in a P2V conversion process, and comprises: (1) designing a local P2V conversion method, wherein a physical server is converted into a local virtual server by configuring a corresponding virtual key, the local virtual server shares underlying hardware resources of the source physical server, thereby avoiding a time consuming magnetic disk copying and synchronization process in a conventional P2V conversion method; (2) a magnetic disk synchronization module, wherein a virtual machine image is initialized on a remote virtualization platform, the mirror image is synchronized with a mirror image of the local virtual server, magnetic disk copying is performed during operation of the local virtual machine, implicit magnetic disk synchronization is performed during the magnetic disk copying, and this process does not bring about any service failure time; and (3) a virtual machine migration module, where online virtual machine migration can minimize negative effect on the local virtual machine.

Description

technical field [0001] The invention belongs to virtualization and cloud computing in the computer field, and in particular relates to a physical machine to virtual machine conversion (Physical To Virtual Converting, P2V) method oriented to server integration. Background technique [0002] The use of virtualization and cloud computing technologies in the data center can increase the utilization rate of physical servers, reduce management and maintenance costs and save energy consumption. With the development and popularization of cloud computing technology, more and more applications run in virtual machines. However, there are still legacy applications that are deployed on physical machines and cannot take advantage of virtualization and cloud computing. How to effectively convert physical servers containing applications to virtualization platforms has become a challenging problem. [0003] The physical machine to virtual machine (P2V) conversion method can realize the int...
