[opensuse] Xen: Is it Ready?
I have a situation where I need Windows & Linus running at the same time. I currently have Linux (server & workstation) running on my server hardware and Windows (workstation) running on a network connected laptop, a satisfactory workaround but hardly a long term solution. I'm thinking of using XEN to run both Linux & Windows on my server hardware. My problem is that no one I trust has actually used XEN in the above configuration. However, I've found that this list gives consistently good info if you ignore the obvious newbies and the occasional flame war. so... Has anyone used Xen running Linux & Windows on the same hardware? If so, is it ready for a production environment? Did you notice any performance degradation? Are there any gotchas that can be avoided? I'd sincerely appreciate answers to my questions and any comments you may have.

I haven't done so myself, but I I did see at a Microsoft Launch Event a month or so where they were showing off Windows Workstation 2003 running inside Xen on SLES. I've heard from Brainshare that the fastest way to run Windows 2003 is from within Xen. -- kai www.filesite.org || www.4thedadz.com || www.perfectreign.com remember - a turn signal is a statement, not a request -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Really..?? Or do you mean xen runs windows 2003 faster than other virtual machine technologies..? mj -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

On to what I have heard about win 2003 running faster in XEN. I have been told that it runs better on XEN as in its more stable . I will know soon. maybe by this time next month I will have my server upgrade approved an will be able to let people know shortly after that. jack -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

This seems counter intuitive. What in xen could recover from instability in Win 2003 itself? -- ----------JSA--------- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

No matter what hardware you're running on, Xen is providing the same (virtual) hardware that W2003 thinks it's running on, so it could be the most debugged "hardware" for it. Alternatively, Xen just emulates a selection of hardware on which Xen is particularly stable. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Of course this explanation suggests that hardware faults are the cause of Windows instability or slowness when running nativly. I find that very difficult to believe. And it still does not explain why the claim is made that Windows runs better under Xen than it runs naively. Hardware faults, to the extent they exist, would be still there. -- ----------JSA--------- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The big difference I can think of is drivers. It could be that the Xen drivers are more reliable than the ones from the various hardware manufacturers. Video drivers in particular always seem like a source of problems with Windows.

I'm fixing to go down that road here myself, we are upgrading our servers an plan to run SLES on both servers with XEN an have a mix of windows an linux vm's running on top of SLES. Granted we will also have netware util's an groupwise running on linux vm's. I have heard that win 2003 runs faster on XEN then on a hardware server also. jack -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I've been running a windows machine using the free Vmware Server inside my OpenSuse server for months on end with no problem. It boots and shuts down when the server boots and the tasks it has to run are in the startup folder. The windows VM runs essentially headless but can be accessed via the remote console from anywhere. Absolutely reliable as far as I can tell. Speed-wise its adequate, but I can't be sure its comparable to hardware. -- ----------JSA--------- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
For most workloads Qemu/KVM will give you excellent results, without the hurdle of messing with special Xen kernels. Try KVM. -- -Alexey Eremenko "Technologov" -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Does VMware need a new kernel?
Here's my problem I have alot of remote servers and I really want to
test Xen (I have it installed on one actually) but it requires me to
bootup with a diffrent kernel, something I don't want to do without
the machine in front of me, incase it crashes.

If you're doing remote system maintenance, is not a practical necessity to be able to remotely initiate a low-level (hardware) reset? Even if you make no configuration or operational mistakes, systems crash, hang and, in general, sometimes require a hardware reset. How do you plan to handle such an eventuality?
