| dc.description.abstract | Virtualization technology helps user create a virtual environment which contains virtual machine that able to execute guest OS on the operating system currently running on a physical platform. Guest OS inside the virtual machine will use the virtual hardware device provided by virtual environment, just like a exclusive hardware environment for it. With sheltering of such technique, the security of system, resource allocation and management of cluster systems can significantly improve.
With supports of hardware that performance increasing every day, the applying of virtual technology is indeed very practical and effective; virtual platform installation is also very easy to take action. however, taking into account the existing operating system running on the physical hardware, at present the only feasible way to switch platform from physical to virtual, is to reinstall whole operating system and re-deployment all applications. Clearly, this approach cannot be directly, effectively and efficiently use by the operation system on the existing machine.
This paper present a solution for lively migrating of running operating system from physical platform to virtual environment, and discussed in detail the steps in which to study the feasibility of the various steps. provided through the program dynamics of migration - in progressing of moving, the process and operating system can maintain its execution - many cannot tolerate disruption of system operations, such as: the operation takes a long time scientific computing, real-time response to network services ... and so on, will be able to maintain the progress of the previous operation, at the same time, the system platform switch from the physical to the virtual machine environment.
