Novell To Ship Xen in Next Version of Suse
daria42 writes "The next version of SuSE, to be shipped in mid-April, will ship with the Xen virtualization software, letting users run multiple versions of the operating system simultaneously, the company said on Thursday. The article says that Red Hat has also begun adding Xen support to Fedora."
Simple question. ("normal users").
Sorry, who?
How does Xen compare to User Mode Linux? They appear to scratch a similar itch, but has anyone tried out both to compare?

The virtualization software makes it much easier to build task-focused servers, helping add more security to your environment... with very low overhead.
Has anybody done a 1-to-1 comparison between Solaris Zones and the features that Xen provides? The Solaris setup is really very easy.. you can have a custom environment booted and running in a few minutes..
I will say that Xen is impressive, given its benchmarks posted.. it shows a very efficient virtualization engine.
Of course, I understand the licensing and freedom restrictions about using Windows under such a program, but without being able to use Windows with it, I'm gonna have to stick with VMware.
I can see the uses for it, but right now, those don't align with what I need, and I suspect that will hold true for many others as well.
Even still, it's cool technology.
Find out about the Lexus Rx400h Hybrid!
Also, combined with other code like emulators it can even go further than just virtualizing x86 software.
How exactly does Linux in a VM run Wine better than Linux not in a VM?

You take 10 machines. Install 10 copies of Linux or NetBSD on each, using Xen to run them simultaneously. Then you make 10 beowulf clusters out of it.
It is interesting to see that Microsoft earlier supported Xen, but then later pulled support. Their (Xen's) homepage still mentions having received support from Microsoft Research.

Parent post is pure, unadulterated bullshit.
You don't install Wine into a virtual machine any more than you install Office or HalfLife into a virtual machine.
You install an OPERATING SYSTEM into a virtual machine, then you install applications on that OS.
Wine is an application, no different than OpenOffice. It uses the services of the underlying operating system to do its job. The fact that its job is to provide the APIs of a foreign operating system is incidental.
So, all that running Xen would do is to allow you to have an install of Linux or *BSD solely to run Wine - which would provide no real benefit to running Wine.
The only way in which Xen would be of use in running Windows programs would be if Windows ran under Xen - which last time I checked it DOES NOT.
The poster of the parent post is just trolling for stupid moderators, and obviously has already found at least one.

What are you talking about ? Can you elaborate or are you just throwing around some nice sounding phrases ?
They're planning on shipping KDE 3.4 when it's released, or they're including the current RC?

Does this mean you have to pay extra for each instance of suse you run under Xen?
A distro added a package. Why is this being reported on slashdot?
A good use for this sort of thing is letting normal users onto a pc without making a mess of it, think:
"Xen and the art of computer maintanance"
It's faster, but with current hardware it needs support from the guest OS. You basically need to build the guest kernel to run within Xen.
This is fairly straightforward for open-source OS's, but is why you can't currently run windows on top of Xen.
Lets you try out new distros or OS with ease.
Allows you to partition a computer into many virtual machines.
Want to give 10 people there own servers to play with? Just use Xen. Great for ISPs.
The real question is what do you mean by a "normal" user. Just because you do not have a use for it and you might not does not mean that many people will. I have no use for AIM but I know some people seem to.
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
iTunes already works in Wine. There has been some significant development to get it working more smoothly lately, especially in Crossover Office, but also in the vanilla Wine tree. No idea about the other app you mentioned, I've never heard of it, but it's probably worth giving it a whirl in Wine.

1.4 Does Xen support Microsoft Windows?
Unfortunately we do not currently support Windows; the paravirtualized approach we use to get such high performance has not been usable directly for Windows to date. However recently announced hardware support from Intel and AMD will allow us to transparently support Windows XP & 2003 Server in the near future. We are working on this and intend to have support available by the time the new processors are available.

Why?

Novell Marketing, the biggest bunch of punching bags in the history of the technology industry, has gotta be asking themselves, "Why us?"
QEMU looks like a worthy replacement for VMWare, especially given the recent release of the accelerator module. Fabrice is hoping for corporate support of the project, and IMO he is as deserving as anyone.
See, there's a vast uber-wing conspiracy among the internautti to waste the time of hard working productive people like yourself, who have so little time during the day for keeping up to date that they don't have time to read headlines, only stories, and thus when you read the story directly and find you have wasted your time, and then post on slashdot to complain about it, the internautti cackle with glee at another success story.
The answer, of course, is to read the headlines first, not read the stories just because they are available, and not play the internautti's game. Eventually, if such a radical notion spreads far and wide, or even short and narrow, the internautti will be disillusioned and find some other amusement.
Infuriate left and right
This is multiple Linuxes running on a VMM: Virtual Machine Monitor. The Linuxes run side by side, none run inside each other.
The technique takes advantage of the multiple rings (0-3) on Intel. Normally Linux (and other kernels) run on ring 0, but with Xen the Xen VMM runs on ring 0 while Linux and other guest OSs run on ring 1, while user-mode programs continue to run on ring 3.

> Well separation of states and state flow for one
Yes, but won't the impedance mismatch between the flow and the state potentially result in a performance penalty? I would think that one of the most significant properties of this environment would be that the system resource flow rate is constant in a steady-state flow system. This means there would be no accumulation of resources within any component of the system.
when will people start pronouncing SuSE correctly in the workplace?
I'm sure I'll hear Xen called "X-men" at some point.
There's a separate root directory for each vserver, which means one can install whatever Linux distribution one wants in there, as long as the distribution doesn't depend on a special kernel (it shouldn't: near-metal operations will be done in the host kernel). Your argument is at fault here.
There's only one kernel instance running though, which is your point I believe. Xen seems to support non-linux OSes such as FreeBSD.
Well, because it's fast for one thing.
Life is about tradeoffs. One of the biggest things you give away trying to create a virutal server is speed. Xen's advantage is that it is more efficient.
Suppose I want to run a name server and a database server, and I only have one physical box to do it on. In a sense, running them on the same machine introduces a kind of coupling. If BIND turns out to have a remote root vulnerability, my database is toast. I'd consider running under vmware, but the performance hit is big enough that I'd probably decide to live with the potential problem.
I can imagine in the future a distro in which a separate virtual machines is used when the user decides to browse the internet or read email, provided the overhead was small. When his browser machine is rooted by spyware, they can enjoy looking at his bookmarks, because that's all they're getting. If the user screws up and installs a trojan popup extension, he can throw the entire virtual machine away and get a new one off the shelf.
Post may contain irony: discontinue use if experiencing mood swings, nausea or elevated blood pressure.
True, there is no license fee for 'core' Linux, but if you run any of the VAR components of distribution X, there might be some licensing issues.

> Well, why would you want power management on a virtual machine? the host machine should manage the power...
Never used Xen, have you? You have to run a Xen-patched kernel as the HOST system, and THAT is what doesn't
support power management. i.e. if you're running Xen, you cannot simultaneously use any power management features
of your hardware.
