Xen
From ReactOS
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.
