[opensuse] Xen vs KVM
I bought a new motherboard for my wife's computer, making sure it (Gigabyte GA-P55-UD3) and its processor (Intel i5-650) supported both vt-x and vt-d. Recently I've read in a techno-blog that Xen is dead because of KVM. Suse ships Xen, and I'd intended to use it, but this guy speculates that Novell is only sticking with Xen because of its relationship with Microsoft; other distributions are already switching to KVM. Is there a firm answer to the value of Xen vs KVM? I've done some preliminary reading, and both look good to my uninformed eye. Are there any present advantages to Xen due to suse's direct support in the distribution? Is there risk that I might have to dump Xen in a year and rebuild my system with KVM? Are these questions worth asking :-)? John Perry -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

While KVM has it's advantage due to it's inclusion in the kernel (doesn't need different kernel like Xen), Xen are quite mature and stable and you should go with Xen.

Your question are worth to be asking, and the following article from Zonker may give you a better answer :-) : http://www.linux.com/component/content/article/153-systems-management-/32762... Just to make it simple, openSUSE 11.3 (and also SLES 11 SP1) ships with both Xen and KVM. -- Best Regards, Masim "Vavai" Sugianto /************************************************************/ Blog (ID) : http://www.vavai.com Excellent Infotama Kreasindo : http://www.vavai.biz /************************************************************/ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

My personal opinion is that KVM has the greater momentum so over time I expect it to gain over Xen. Today, KVM has for me one clear advantage: I can run it on my laptop without the need to run a hypervisor etc. Today Xen is the more mature version and if you have critical workload on your servers, I advise Xen. If you want to evaluate what virtualization to use in the future, consider kvm, Andreas -- Andreas Jaeger, Program Manager openSUSE, aj@{novell.com,opensuse.org} Twitter: jaegerandi | Identica: jaegerandi SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

Thanks, Vavai and Andreas. This is just for my wife's computer (my work laptop doesn't have the vt extensions, so I'm working on bringing up virtualbox), and what I'd like is for her to be able to use Windows xp pro while I'm using suse. I'd also like to try out things like QNX, Hard Hat linux, and such, all while letting her do her work in xp. Might this influence my path? Or am I overestimating what a virtualization system might do for me? Some other replies seem to imply that they can't run together without the "windowing under suse" feature enabled. I'm not sure I can talk her into that. jp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I don't understand what you mean by "windowing under suse" Although I have not done it - I believe It is possible to run a GUI desktop on a host OS in runlevel 3 with the VNC option in qemu-kvm.

I take it that you have a dual boot system with XP and openSUSE? You can run XP in a VM with openSUSE has the host OS :) -- Arun Khan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
I guess I was too concise in my questions. On 08/06/2010 03:18 PM, Arun Khan wrote:

Replies to questions in other threads have implied that Windows applications will run in windows in the host OS (suse, here). Not understanding any details yet, I asked if that was necessary (I'm in chapter 2 of the user manual, not having been able to get through any of the "easy how-to's"). What I want to do is let her run her Windows xp at the local terminal under the suse host without her having even to see suse in evidence. At the same time, I want to vpn from my laptop into the suse host and use the high-power resources on her computer for some of my work. I want to run the two OS's simultaneously and independently (from the user's perspective, of course -- I know xp depends upon suse/xen).

Yes, both xp and suse are installed and running perfectly. Xen is installed in suse, and I'm trying to figure out how to make the two work together. Running xp simultaneously with suse is exactly what I want to do, as I spelled out above. jp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
