Dune

Dune provides ordinary user programs with safe and efficient access to privileged CPU features that are traditionally only available to kernels. It does so by leveraging modern virtualization hardware, enabling direct execution of privileged instructions in an unprivileged context. We have implemented Dune for Linux, using Intel's VT-x virtualization architecture to expose access to exceptions, virtual memory, privilege modes, and segmentation. By making these hardware mechanisms available at user-level, Dune creates opportunities to deploy novel systems without specialized kernel modifications.
