Xen

From ReactOS

Jump to: navigation, search

Xen is an open-source virtual machine monitor, or hypervisor, developed by the University of Cambridge. It has a design goal of being able to run 100 full-featured operating system (OS) instances on a single typical computer. Xen provides secure isolation, resource control, quality-of-service guarantees, and live migration of virtual machines. Xen can run operating systems in two modes:

  • Para-Virtualized mode needs modified ("ported") guest operating systems but works on any x86 hardware.

Compatibility is maintained for user applications. This enables Xen to achieve high-performance virtualization without special hardware support.

  • fully virtualized mode or HVM mode needs AMD Pacifica or Intel Vanderpool compatible hardware. It is not as fast as para-virtualized mode but it can run unmodified guest operating systems like Windows XP.
