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").
Belief is the currency of delusion.
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?

Well separation of states and state flow for one
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.

So in order to boot up you need to be a quantum physicist wearing bright orange armor wielding a crowbar and jump from floating rock to floating rock in the world's most annoying jumping puzzle only to confront a four-legged spider and the big floating baby?
How is this different from projects such as Linux-VServer? http://linux-vserver.org/
How does Opensource software Xen measure up to other virtualization software like VMWare and others I even do not know? Are there more anyway?
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?
Game! - Where the stick is mightier than the sword!
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"
I fully understand a usefulness of linux on linux, as well as other virtualizations.
That said, when can I get WINE or something similar working sufficiently so the few things that keep me having a windows box around can fade away? I'm not even talking games - I really just need audiblemanager and itunes running. Neither of these should be hard at all.
I'm almost tempted to buy a mac mini just so I can get this functionality without the windows factor.

UML's performance sucks in some situations such as OLTP benchmarks.
You have (or had to in the past) patch UML so that you couldn't tell you were in UML (applicationas and the UML OS shared the same address space).
I'm curious if anyone has done any realworld comparisons with Xen and Virtuoso?
Novell is actually really good at implementing good products and features, but their marketing and licensing sucks. I didn't think that used to matter, but trying to get CIO's and other pointy-hairs to put the product on the same playing field as M$ is annoyingly diffcult due to Novell's business-side ineptitude (or clever no-marketing strategy, you be the judge).
If they cannot release the code so that others can use it, then the fact that they have Windows working under Xen is not terribly relevant to the discussion at hand.

I fully understand the reasons why Xen doesn't run Windows as a guest operating system, but I still find it a damn shame. It could be the perfect open source replacement for VMWare, and it would make a hell of a lubricator for Windows-to-Linux migration projects.
8 of 13 people found this answer helpful. Did you?
So how long do you think before they perfect running NetWare under Xen?

Eh! you don't leave much space to imagination, do you? :-P
as several features, notably any APM or ACPI power management at all, don't work with Xen at the moment.

...to running Linux in something like VMWare ESX (not GSX!)?
As much as I like Suse and Xen....I wonder if it's really stable. Suse's historial has several "addons" to the kernel, like CKRM and XEN. Is not that those projects are not great....but they are not included in the kernel.org kernel...they have been submitted but there's "work" to do. Suse is free to ship whatever they want - this is open software - but running software which is still not good enought to be included in kernel.org...scares the sh*t out of me. It's still being cleaned up, doesn't have a lot of users...i'd say it's in "beta" stage: "works for most of the people, but..."
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.

from Gordon Freeman himself!
Well, staying true to his silent methods Mr. Freeman had nothing to say, but instead grabbed his trusty crowbar and walked out the door, without so much as saying "Goodbye".
Our reporter, however, believes that this, a second, or possibly third attempt by Xen to invade the Earth will be stopped cold in its tracks!
If you don't know what AltaVista is (was), get off my lawn.
Why?
Zen... Xen... Zen... Xen... Zen... Xen...
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.
NOVELL SUPPORT: "Thank you for calling Novell Support. How may I be of assistance to you today?"
CUSTOMER: "Uh, my syslogs are telling me that I've got a problem with something called [insert hard sibilant here]-en".
NOVELL SUPPORT: "Sir, is that [insert hard sibilant here]-en with an 'X' or [insert hard sibilant here]-en with a 'Z'?"
CUSTOMER: "Huh?"
Was it removed or was considered not as important as the other announced features?
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.
We now need a "performance shootout" comparison of Solaris zones, FreeBSD jails, and Zen on Linux (or other Unix systems).
Who's going to be the first to undertake this task?
Nice Troll!
I don't really understand why they are supporting Xen so much. IMHO QEMU would be a better choice. It's much more faster with [and without!] the accelerator module...
Red-hat, Suse wake up!
Somebody's been watching too much Atlantis.
Virtual Private Server hosting providers could use this. I believe most of them are using User Mode Linux. Mine is. That would benefit those of us who need that level of hosting.
I can see the problem with this right away - if anybody uses this their license fees will go through the roof!
"Provided by the management for your protection."
"It could be the perfect open source replacement for VMWare, and it would make a hell of a lubricator for Windows-to-Linux migration projects."
Ladies and geeks. This is why you can't make money with OSS. Whatever you're selling, someone will try to commodatize it. Plus the undermining of the whole Linux market by removing any incentive for people to leave Windows.

They all 'autorun'. Most of them 'boot', too. Have fun !
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.
---- Booth was a patriot ----
Sure, installing multiple operating systems for the fun of it, but I think it would be more challenging adding support to a single operating system to smoothly support multiple graphics cards and keyboards letting several users share a single computer for the fun of it.
How does Xen compare to Plex86?
For Linux-On-Windows, how does this compare with coLinux?
I finally purchased my copy of SuSE 9.2 and now 9.3 is almost shipping? Didn't 9.2 just come out?
I hope Novell adds plenty of bandwith when they offer 9.3 as a DVD ISO for free download. The 9.2 FTP DVD ISO always crapped out on me, thus my purchase.
Maybe he's thinking about tracing windows system calls, so they can be emulated better?
That would probably work better with something like QEMU since it runs entirely in user space, and might be easier to trace than with XEN.
