Dave Lively Steve Ofsthun and Dave Liveley Virtual Iron Running Xen diskless ****** Deploying Xen and domain 0 in a diskless "embedded" environment has several desirable properties but also raises some new challenges. This presentation describes our Xen-based hypervisor and domain 0 deployment into a couple such environments, as well as the motivation for doing so. It addresses the various issues we faced, including: * where to keep persistent state * limiting dom0 memory footprint * Linux buffer cache issues * control stack issues We'll also talk about maintaining a "downstream" code base, mistakes made, and lessons learned.
