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.
