Abstract

Virtualised systems have experienced a resurgence in popularity in recent years, particularly in supporting a large number of independent services on a single host. This paper describes our work designing and implementing Proper, a service running on the PlanetLab system, that allows other services to perform privileged operations in a safe, controlled manner. We describe how implementing such a system in a traditional UNIX environment is non-trivial, and discuss the practical use of Proper.
