[Xen-devel] The right way to get an actual xen-enabled kernel-source tree?
Hello list, I need a xen-kernel in version 2.6.28, but can't find any hint, how i can come to this point? AFAIK the xensources stopped with 2.6.18? So what'S actual the way to get a vanilla-kernel and patch it with xen?

Thanks a lot for the fast answer and yes, i need it for dom0! Does this "pv_ops"-way mean, that i would have to use an not productional usable kernel? So perhaps it would be better for me, to patch a kernel with the 2.6.18 patchset? If it is usable: As i never used git before, could you please provide me the commandline to use it for a 2.6.28 kernel? Is it like patching in that way: 1. download 2.6.28(.rcxx) vanilla-sources 2. untar and go to that directory 3. do "git something" now?

AW: [Xen-devel] The right way to get an actualxen-enabledkernel-source tree?
Thanks again ;) Reason for 2.6.28 is, that i was told by xen-users that 2.6.27 from SLES is buggy and after tests, i could approve that. Additionally, i was told that 2.6.28 with xen support is stable. Unfortunately, nobody could tell me until now, where i could get that mysterious 2.6.28-xen-kernel, so that''s why i am asking now here.. As i am using gentoo, i would need a source-tree to compile the kernel for me, prebuild binaries wont be from help. I didn''t find any not sles-xen-kernel-source (src-rpm) in higher versions, p.e. by redhat to "steel" this ;) I tried the "lenny"-way, but debian makes some strange things in the kernel-source packages that i don''t understand in result as non-debianist, so i went back again to the roots and wanted to take the good old vanilla-source and patch it ;) What is your advice concerning the stability of jeremys pv_ops enabled git-sources concerning stability? An absolute no-go, or is it near stable, just waiting for some last checks?

If possible keep it until pvops kernel will merge mainline Linux. It works for xen user''s development. There are several howtos regarding proper config for Novell''s 2.6.27 xen-ified kernel on the Net. In particular, it does load under Xen on Intel''s Q95XX CPUs --- On Fri, 3/6/09, Keir Fraser <keir.fraser@eu.citrix.com> wrote: From: Keir Fraser <keir.fraser@eu.citrix.com> Subject: Re: AW: [Xen-devel] The right way to get an actualxen-enabledkernel-source tree?
