Its actually not a virtual machine running on linux - its linux running on a hypervisor. In the current stable version it supports linux 2.4 or 2.6 as the managing domain, and 2.4, 2.6 netbsd and freebsd as other domains.
In the past an experimental port of windows was made to an older version of xen, but as far as i can tell it was done under a research liscense from microsoft and cant be released.
In xen 3, they are planning on having support not only for running modified guest domains, but also running any unmodified system.
Xen does have a lot of cool virtual machine features that you wont find in the standard kernel, or anywhere outside of a Z series machine. One of the nicest things that hasnt been meantioned here yet is the live migration of domains. That was what initialy made us look at xen - as a system to facilitate hardware upgrades of comodity servers without woring about the downtime it will cause your services. If you have all your services running as xen domains, you can migrate them to another physical computer on the same subnet, with no downtime of your network connections. Any users connected wont even notice the slight(200ms) pause in the domain as the last memory pages are swaped over. Another nice feature of xen is its amazing speed. In our tests at COSI, we found that there was only a 5-10% performace hit by running a database or webserver in a xen domain instead of nativly, completly destroying VMwares perfomance numbers. If you want more information about the performace aspect, you can find a couple of papers that have been written by other COSI members on the COSI webpage about xen.
The site doesnt have much information on it yet because it just went live last night. The main point was to just get the distribution out there to the people who already know what xen is, so that they can help test it.
Xenophilia isnt so much a new distribution, as it is a hacked set of debian installer packages that replace the kernel installation stages with a new set of stages that install and configure the xen hypervisor and the xen kernel for domain 0. All the other packages are identical to the debian packages from sarge.
If you had throughly looked at the site you would have noticed the plethora of links to additional content; tutorial that we wrote, and the origonal xen documentation, that give you all the information you would need about xen.
Since we based Xenophilia off of debian, you dont have to worry about us dissapperaring and you loosing support. Once the base system is installed, you can just point your apt sources at debians servers and use their packages if you desire.
We came up with the Xenophilia name, becuase the distribution is meant to bring togeather any distributions you want as other domains running on the system.
every ipod since the second generation has worked with windows. you can mount the ipod just like any normal firewire drive so of course it works with linux. (the first generation ipods were HFS filesystem only, so you could probably get them to work with linux, but i doubt windows)
hum... the G4s are now at dual 1.25ghz osx IS unix, its not jsut a few unix applications, its all unix applications
of course you can boot without the gui, its just a few processes, just dont have them start up! and that weird microkernal is mach, its been around for a while and presents an intersting way of doing things, but still presents the same interface to YOU as the end user, you can use standard POSIX calls just like on any unix, and they are native.
why do i have to hate computers to love apple? im typing this on a tibook, and it is the best engineered laptop i have ever used. apples hardware may not be the fastest, but in usablity and reliablity it kicks ass.
where do they get the idea that c# and J2EE dominate the market now? i still see a lot of development with c or c++ for speed reasons. Java may be a great language in theory, but it still has issues with speed over a native language.
the fastest processors on terms of clock speed may be the p4 and its multigigahertz, but think of all the other processor lines that are MUCH faster at lower clock speeds computationaly wise(powerpc-power4, alpha, itanium...)
just like that mac HFS filesystem is, as the artical points out, if you touch foo, and then touch Foo, it will give you no errors, but when you look at your dir listing, only one file Foo will exist, but you can access it by Foo, fOo, fOO...
if you cant find an existing organization that fits your needs, why not start your own? im sure there are plenty of fellow geeks here who would love to join somthing just like what your looking for.
its intersting to see how much the focus seems to be on providing better support in the kernal for large server features, instead of making the experiance of using linux on a normal desktop box easier and more efficient.
wow, im amazed anyone could spend the time to calculate that by hand, belive me, ive tried and after a few points it gets really really boring, i commend him for his effort, but must say im glad i have a computer to do it and dont have to waste a few years doing caculations by hand
umm... i think leo was just trying to be a bit sarcastic. as in how would the platypus ever represent an evolutionary advantage? sarcasm sarcasm sarcasm, damn we need inflection in printed speech
i worry about these projects that advertise almost no cnfiguration needed, anyone running a large system should know how to configure and manage the system to be secure and efficient in their own environment. people shouldnt be lured into thinking that their system was safe bc it had a good default instalation
why stay under their employment if you cant agree with their morals and ethics? if your not happy with what your doing go find a new job, let someone else do the work you know is wrong
yes, and humans have evolved to the point where they can explore other means of surviving besides adaptation, we can change out exvironment, and fix the flaws in our bodies ourselvs now

that page shows santovac 5 in 100CC bottles for $160, therefore it is $1.65 per ml not over $100 per ml
A .5% resistor is not all that impressive. Look at a the Susumo Co part number RG1005N-101-P-T1 which is a 0.02% 100 ohm resistor.0 1.pdf for more info

so its just like different citues have different sized subnets on the network. makes perfect sense to me :)
if your willing to spend 500, why not just get an ipod and steal the hard drive from that? you even can get a 20 gig one for under $500

i dont think hes going for smaller files, but better sound, therfore why not a format like AIFF or even... .wav, it may make huge files, but who cares?

oh darn! I used my hand to copy a protected work. does this mean an injunction will be filed against me using my hand?
