User-mode Linux

Jeff Dike

Abstract:

User-mode Linux is the port of the Linux kernel to userspace. It runs a Linux virtual machine in a set of processes on a Linux host. A UML virtual machine is capable of running nearly the same set of processes as the host. It lends itself to a variety of applications, such as kernel development, security applications like sandboxing and jailing, and virtual networking. This paper describes the design and implementation of UML, current and future applications for it, and future work.
