 | | Denali uses paravirtualisation to provide high-performance virtual machines on x86 computers. | | | Xenophilia is a Linux distribution that is based around Xen. | | | The primary benefits to virtualisation include extracting the most work possible from a single machine, and securing software programs through the use of separate virtual operating systems (similar to using a chroot jail, but more secure.) Virtualisation can also be used to run different and incompatible operating systems on the same computer. |

| | Xen is the industry-standard open source infrastructure virtualization software created and maintained by the founders of XenSource, Inc., and developed collaboratively by over 20 of the world’s most innovative data center solution vendors. | | | Xen 3.0 supports Intel® Virtualization Technology, which allows virtualized servers to run natively on the processor, exploiting hardware acceleration for CPU and memory virtualization. | | | Xen’s ability to instantly deploy a virtual server image on any server dramatically cuts provisioning time – from weeks to seconds – and its live relocation capability enables no-downtime maintenance, high availability and optimal matching of workload to available compute resources. |

| | Xen is a "hypervisor"--a thin layer of software that governs how different operating systems get access to computer resources such as processors and memory. | | | Xen, software that lets multiple operating systems run on the same computer, will become significantly more powerful with an upcoming version that introduces multiprocessor support. | | | Mainstream adoption of multi-OS practices likely will be hastened by features in Intel processors this year and Advanced Micro Devices chips in 2006 that make the task significantly easier. |
