Design and evaluation of a system for running two coexisting Linux systems

Abstract

AbstractA method to independently run two coexisting Linux systems on one computer is proposed. Up to the present time a virtual computer method has been used as a method to run multiple operating systems on one computer. This method has a problem, however, in which the guest operating system depends on the running state of the host operating system making it impossible to efficiently utilize the processing performance of each operating system. In contrast to this, because each operating system runs independently in the proposed method by time sharing the processes and exclusively dividing the other hardware resources, one of the operating systems and applications running on the operating systems are not influenced by the other operating system and the applications running on the operating system. This paper presents the proposed method and reports the results of performance evaluations when actually implemented in Linux. © 2007 Wiley Periodicals, Inc.
