The Research & Implementation of Xen-Based Operable and Secure Virtual Environment

This paper studied the general principle about Xen´s virtual network environment structure and the response process about character device during full visualization. In view of the network security and feasibility problem of Xen, we proposed the multiple-network isolated virtual network environment and an operable security switching system, which are implemented so that it can effectively safeguard the security and feasibility of Xen virtual environment.
