To achieve such high performance, Xen requires that OSes are ported to run on it. See the Current status of OS ports The paravirtualized approach we use to get such high performance has not been usable directly for Windows to date. However Xen 3.0 added Intel VT-x support to enable the running of unmodified guest operating systems, including Windows XP & 2003 Server, using hardware virtualization technology. Xen 3.0.2 and later support AMD Pacifica technology as well.

Well, you can opt for the M2U without an accompanied modem. Although, we do strongly recommend that you use the GPRS modem we provide, this is to ensure 100% compatibility and stability.

Xen is a virtual machine monitor (VMM) for x86-compatible computers. Xen can securely execute multiple virtual machines, each running its own OS, on a single physical system with close-to-native performance.

It should run on most Unices as well as Windows versions (including Windows NT/2000) and Macintosh OS/X. A list of OSes reported to be OK is presented at:

Xen is Open Source, and is released under terms of the GNU General Public License. Operating systems or other applications written to use Xen's hypercall interface are not derived works of Xen, hence may be licensed differently.

There is both paid and volunteer support available for Xen. Commercial support is provided by Citrix Systems, Inc. (XenSource, Inc.), the proprietors of this wiki. Volunteer support is available via the Xen mailing lists and on Internet Relay Chat (IRC): channel ##xen ("about Xen") on irc.freenode.net is a slightly larger, unofficial channel which also provides support

Xen currently runs only on the x86 architecture, requiring a "P6" or newer processor (that's any Intel or AMD x86 CPU purchased in the last five years). Multiprocessor machines are supported, including basic support for Hyper-Threading (SMT). Support for x86/64 is available since Xen 3.0. In addition a port to the IA64 architecture is approaching completion. We hope to add other architectures such as PPC and ARM in due course.

To run Xen and a single OS from a binary release you need install no extra packages. To build Xen, XenLinux and documentation from source you will need: make, libncurses5-dev, libncurses5, gcc, libc6-dev, zlib1g-dev, python, python-dev, python-twisted, openssl, openssl-dev, bridge-utils, iproute, libcurl3, libcurl3-dev, bzip2, module-init-tools, latex, latex2html, transfig, and tgif.

Currently, only a DOS version of ALL is available. However, after I'm completely finished with the DOS version, I plan to port ALL to Windows as well as to Linux. I'd like to port it to MacOS as well, but I don't have any Macs to test ALL on and I don't know that much about Macs in the first place, so I don't know if a Mac port will actually happen or not.

Modifying a kernel source tree to run Xen is not a simple task. It might seem that one should be able to run a few patches on any kernel and make it a Xen kernel but this not the case. Currently, the best option is to look to the distribution vendors. For instance, Fedora 7 ships with Xen 3.1.0 and kernel 2.6.20. Fedora provides source RPMS that might be of interest to anyone who wants to build their own 2.6.20 Xen kernel.

There are various forms of initrd image, but the two most common formats are a gzip'ed filesystem and a gzip'ed cpio file. In either case you can take the following steps to modify a file initrd.img (when running as root): mkdir initrd.mnt # gzip -d -S ".img" /path/to/initrd.img # mount -o loop /path/to/initrd initrd.mnt OR (cd initrd.mnt && cpio -ic <../path/to/initrd) # ...edit files in directory initrd.mnt.... # umount initrd.mnt OR (cd initrd.mnt && find .

Our Xen servers are currently hosted in Scolocate, Edinburgh. Scolocate is Scotland's only carrier-neutral datacentre and a major Internet hub point for telecommunications carriers. Our technical team and office are located in the Datacentre building.

You can certainly use a disk image used by VMware and use it in Xen, in the same way you can move a hard drive from one physical system to another.

Yes. A good whitepaper on virtualization and the difference between virtualization technologies is What is Virtualization?, conveniently available from Red Hat.

While both companies can supply complete turnkey solutions like SKY MobileMedia, their software is focused exclusively on the highest-end smartphones and PDAs. Their memory footprint, applications processor requirements, and licensing costs preclude their solutions from being used in cost-sensitive low-cost handset and feature phones, the largest and fastest growing segments of the market.

Quick and easy, copy chain0 to the root directory of your bootable Windows drive, then add the following the bottom of your "boot.ini" file: C:\Chain0="Mac OS X86" this however renders the Quiet Boot option useless, so if the Darwin loader annoys you as much as it does me then add this to the bottom of your "boot.ini" instead: C:\Chain0="Mac OS X86" "Quiet Boot"="Yes" I do not mess about with boot loaders. I run XP and OSX. I boot from pc BIOS F11, which enables boot from any available disk.

Yes. BeleniX uses the Grub bootloader that allows you to boot other operating systems. Currently BeleniX will install it's own Grub into the MBR and overwrite the original bootloader. The Grub configuration file in BeleniX is /boot/grub/menu.lst which can be modified to add entries for other operating systems. This will be changed in a subsequent release to allow the option to install Grub into the Solaris partition and to auto-detect other bootable operating systems.

When I tried to register I get the message "The Book Title and/or ISBN you entered do not correlate." When registering for one of the Online Student Editions (OSE) you receive the following error: Please ensure that one (and only one) book title is selected from the pull down menus.

Solution: The online versions are best viewed with Adobe Acrobat Reader Version 5.x. You can download Acrobat Reader for free by going to www.adobe.com/products/acrobat/readstep2_allversions.html. Solution: Usernames and passwords are no longer case sensitive. If you are a teacher and continue to have issues, please register again. Note: Sometime the number zero is mistaken for the letter "O". Solution: Dial-up modems may not be fast enough to access the online student editions.

Yes you can. For example, you could have a single computer, running Xen virtualization, act as a complete cluster consisting of several xen guests. There are special fencing issues to consider. For example, if you use power fencing, one guest could cause the whole machine to be powered off and never come back (because it wouldn't be alive to tell the power switch to power back on). There is a special fencing agent designed to reboot xen guests as needed.

Nope. XEN/UML/QEMU and VServer are just good friends. Because you ask, you probably know what XEN/UML/QEMU are. VServer in contrary to XEN/UML/QEMU not "emulate" any hardware you run a kernel on. You can run a VServer kernel in a XEN/UML/QEMU guest. This is confirmed to work at least with Linux 2.6/vs2.0.

UML uses emulated system calls and emulated disk drivers which make it very slow, especially when it comes to context switches and disk I/O. Xen itself is a hypervisor with the base operating system simply being a VM under it. This makes it have very low overhead (2-8%). Linux VServer is a shared kernel with security isolation so it lacks many features such as no low level networking, IPSec, IPv6, iptables, ebtables, loadable kernel modules, etc.

We use Virtuozzo for our VPS servers. This is because Virtuozzo is mature compared to Xen, and resources are burstable. Virtuozzo also provides web based interface for users to control their VPS, including backup, restore and restart.

an emergency substitute for a packet, you can drink an 8 ounce glass of skim or low-fat milk for each supplement you will miss. Don't do this for more than one day. If you will be away from your Medifast supplies for longer than one day, focus on eating meals that are high-protein, low carbohydrates until you can return to your program. During the first week or so on the program, some people experience diarrhea from the body's adjustment to the concentration of nutrients in the supplements.

You may run or walk. We attract all levels of Orienteers, from casual walkers to competitive elite experts.

Crazy as it may sound at first, yes we do. It's a lot of fun, really. And we hardly ever get injured. Of course, running through the woods is a lot different than running on a road.

First, we think they're fun and we hope you'll have fun participating in our contests. They allow our users to earn climbing gear just for doing something fun: sharing their climbing stories and images. They help our sponsors get the word out about their climbing products, and expose more climbers to their offerings. But we have an ulterior motive. Our contests are a great way to identify the best of the content that YourClimbing.com users submit to the site.
