Xen is a hypervisor based virtualization technology originating at the University of Cambridge, nowadays developed largely by the company XenSource. Xen introduced the concept of paravirtualization, which allows for extremely high performance virtualization provided that the guest virtual machine runs a modified operating system kernel.

Xen also supports full virtualization (running unmodified operating systems) on processors with Intel VT or AMD-V technology.

Xen is available in many Linux distributions, however lhype and KVM appear to be making more progress at getting merged into the upstream kernel...
