[Xen-users] Why Xen will deprecated? Is it to old?
Hello, I''m confused why Xen is deprecated in the next Debian release, does it mean Xen dying? What is alternative? KVM? I''ve heard RH also is going to promote KVM only in a future releases. Can someone elaborate what does it mean? Thank You in advance. http://permalink.gmane.org/gmane.linux.debian.devel.announce/1407 " xen dom 0 +++++++++ This feature will be included in the squeeze kernel release subject to ongoing stabilisation work. The feature will be marked as deprecated and will not appear in future releases. " -- My best wishes. Alexandr Ogurtsov.

Hello, As I understand the mail, it just seems that specific Dom0 kernel will disappear in next Debien stable release. For the time being, when you want to build a Debian Dom0, you have to install a specific "Xen-enabled" kernel. Starting Squeeze, all these functionnalities will be intergrated in the default kernel.

I think it''s because the (huge) Xen dom0 patch is not really maintained for recent kernels. So it''s a hard work to include it in a distribution. But there is actually a big work to integrate this Xen dom0 patch in Linux vanilla, so Xen will not need this hard inclusion work. Squeeze seems to be the last time Debian use the old "2.6.18" patch, but in next Debian (in 2 years) Xen will probably be included in Linux upstream, no ? Olivier Robbie A.

RE: [Xen-users] Why Xen will deprecated? Is it to old?
I''m a little lost as to why people will switch to KVM or that the some OS force one type of software out in favor of another. is it because Xen requires a specific kernel to run? Why so much ''hate'' against Xen? Perhaps it''s my old school thinking but Xen works.... rather well and almost right out of the box for 98% of us. If I have to buy commercial (as I have done for some needs) to keep Xen then I will. Until KVM becomes more of a standard (which if OS keep shoving KVM the way they are... it''s going to happen) I will never switch. ________________________________ From: xen-users-bounces@lists.xensource.com [xen-users-bounces@lists.xensource.com] On Behalf Of Jean Baptiste FAVRE [jean-baptiste.favre@wanadoo.fr] Sent: Tuesday, October 20, 2009 5:42 AM To: xen-users@lists.xensource.com Subject: Re: [Xen-users] Why Xen will deprecated?

Re: [Xen-users] Why Xen will deprecated? Is it to old?
I guess the Debian team will not continue to port forward the old fashion Xen patches (from the 2.6.18...) but, when the mainline Linux came with dom0 pv_ops included by default, the Debian team will just enable the dom0 option... ;-) Cheers!

So, for those who are planing for server consolidation within few months using RHEL 5.4, KVM would be the good choice or there is no harm on sticking with Xen? Paras.

There are xen kernels that work in 5.4. The question is--what is going to happen when RHEL6 comes out. There aren''t any kernel-xen in Fedora 11, just the xen userland. Does anyone know? Obviously redhat is keen to push KVM as hard as they can bue they haven''t said they will actually break Xen, have they?

Upcoming Debian stable release ("Squeeze") will have Xen dom0 using the forward-ported patches. See: http://lists.debian.org/debian-kernel/2009/10/msg00613.html Debian''s plan is to remove the forward-ported Xen dom0 patches after Squeeze, and then use upstream Linux pv_ops dom0 support. -- Pasi> ;-) > Cheers! > Thiago > > 2009/10/20 Pasi Kärkkäinen <[1]pasik@iki.fi> > > On Tue, Oct 20, 2009 at 06:43:30AM -0600, Nick Couchman wrote: > > >>> On 2009/10/20 at 03:42, Jean Baptiste FAVRE > > <[2]jean-baptiste.favre@wanadoo.fr> > > wrote: > > > Hello, > > > As I understand the mail, it just seems that specific Dom0 kernel > > will > > > disappear in next Debien stable release. > > > For the time being, when you want to build a Debian Dom0, you have > > to > > > install a specific "Xen-enabled" kernel. > > > Starting Squeeze, all these functionnalities will be intergrated in > > the > > > default kernel. > > > > > > Regards, > > > JB > > > > > > Alexandr R.

The newest kernels with pv_ops already provide good domU support. Since this is in the official Linux tree, you should be able to use RH6 or any future distribution "out of the box" as a domU. For dom0, run whichever distribution suits you. Someone already said RH5 will be supported for a few years. Or OpenSUSE. Or Debian. Take your pick...there''s no good reason this needs to run the same distribution as your guest domains. For what it''s worth, I have no plans to deploy KVM any time within the next year. If/when KVM leapfrogs Xen in capability and maturity, I''ll take a look. -Jeff _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

If we don''t use any specific Linux distribution like Fedora, Debian, Ubuntu, OpenSUSE, etc, we could still customize or DIY our own linux system according to the instructions here at the Linux from Scratch online book http://www.linuxfromscratch.org/lfs/view/stable/ And then we could download the pv_ops/pvops dom0 kernels and Xen hypervisor and compile ourselves.
