A while ago (I think at the Xummit), I recall someone saying that the structure of the files in xenlinux may change soon so that the xen-specific files would move to a subdirectory or arch/<arch> (e.g. linux/arch/i386/xen instead of linux/arch/xen/i386). Is this still planned? If so, what is the timing? If it''s in progress, I''d like to get in the loop... Thanks, Dan

A couple months ago, there was a thread discussing various opinions for directory structures for including xenlinux code into the Linux tree. (The current structure is not architecture independent and also uses some names/terminology that might need to change to be more acceptable to Linux kernel developers.) I think Chris Wright said at the time that he would be working on a patch to

Is there a list for discussing Rails internals or is that kind of one of those jealously guarded secret things? Also, I seem to be being a bit of a prat today, but if you read this closely: http://www.rubyonrails.org/images/headlines/community.gif Bit of a grammatical error there. (Sorry!) Giles

Hello everyone! With the completion of our first few release candidates for 4.2, it''s time to look forward and start planning for the 4.3 release. I''ve volunteered to step up and help coordinate the release for this cycle. The 4.2 release cycle this time has been nearly a year and a half. One of the problems with having such a long release is that people who get in features

Hey, I''m experiencing strange problem: non-deterministic PV domain hang, only on some machines (with fast SSD drive). I''ve tried xen-4.1.0 and xen-4.1.1 with many kernels different kernels: VM: - 2.6.38.3 xenlinux based on SUSE package - vanilla 3.0.3 - vanilla 3.1 rc2 dom0: - 2.6.38.3 xenlinux based on SUSE package - vanilla 3.1 rc2 Result always the same: sometimes VM

Various versions of Linux under various circumstances select TSC as the primary clocksource for the kernel. This is especially true for uniprocessor kernels, but also in some cases for multiprocessor kernels. In most cases, this is because a processor bit (tsc_invariant? constant_tsc?) is passed through directly from the hardware via Xen and tested by the hvm guest and the result implies that

FYI, it is likely that ocfs2 will not work on 3.7-rcN until the following one-line patch is merged, as the code in ramster that provoked it is directly leveraged from ocfs2 o2net. > From: Tejun Heo [mailto:tj at kernel.org] > Sent: Thursday, October 18, 2012 5:39 PM > To: Dan Magenheimer > Cc: linux-kernel at vger.kernel.org; Konrad Wilk > Subject: [PATCH] workqueue:

I am seeing a problem with Dom0 crashing on x86_64 whenever I create a DomU. I''ve done some more testing, and it appears that this problem is somehow related to networking. Dom0 crashes as soon as the networking services are started when DomU is coming up. As an experiment, I brought up DomU without networking, and it stayed up. As soon as I started DomU with networking enabled, however,

Folks, The second release candidate for Xen 3.4.0 is available at http://xenbits.xensource.com/xen-unstable.hg, tagged as ''3.4.0-rc2''. Please test! -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hmmm... It appears I never posted the corrected version of this patch so it never made it upstream. See: http://lists.xen.org/archives/html/xen-devel/2011-11/msg00587.html http://lists.xen.org/archives/html/xen-devel/2011-11/msg02145.html It would be good if this very minor fix was also applied to 4.2 (and, if possible, 4.1).

Hi Linux kernel folks and Xen folks -- Effective July 5, I will be resigning from Oracle and "retiring" for a minimum of 12-18 months and probably/hopefully much longer. Between now and July 5, I will be tying up loose ends related to my patches but also using up accrued vacation days. If you have a loose end you''d like to see tied, please let me know ASAP and I will do my

Am I correct in reading the code that there is no "noht" (turn off hyperthreading) option in Xen (except in powerpc)? This was a surprise to me as I've seen it documented in various places and I recently suggested it as a diagnostic to a customer. =================================== If Xen could save time in a bottle / then clocks wouldn't virtually skew / It would save every
