Virtual networking in Linux. Computing today is undergoing something of a revival.
Although virtualization was created decades ago, its true potential is now being realized through the use of commodity hardware. Virtualization consolidates server workloads for efficiency, but other elements of the server ecosystem are emerging as candidates for further consolidation.

What distinguishes FAUmachine from these other virtual machines, are the following features: The FAUmachine virtual machine runs as a normal user process (no root privileges or kernel modules needed) on top of Linux on i386 and x86_64 hardware. The port of FAUmachine to OpenBSD is in progress, the one to Mac OS X (intel) is working on both 32 and 64 bit platforms (but is not officially supported, see README.macosx in source for more details). Xen. Xen is an open-source (GPL) type-1 or baremetal hypervisor, which makes it possible to run many instances of an operating system or indeed different operating systems in parallel on a single machine (or host) Some of Xen's key features are: Small footprint and interface (is around 1MB in size).
Because Xen uses a microkernel design, with a small memory footprint and limited interface to the guest, it is more robust and secure than other hypervisors. Operating system agnostic: Most installations run with Linux as the main control stack (aka "domain 0").
