RE: [Users] New Kernel Patch
What does that mean? Well as is obvious to you, as time passes, the number of distributions that are appropriate to use as an OpenVZ host node is reduced... and it appears that RHEL and CentOS truly are the best distros to recommend for the host node. As the type of fanboy I am, that does not frustrate me at all but I realise how frustrating that can be to others. I would indeed call that a limitation. We at Proxmox ended up compiling the RHEL kernel for Debian. So we now have a Debian system with RHEL kernel and OpenVZ. So far that works quite good. - Dietmar ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users

On Sat, Jan 16, 2010 at 12:17:19PM +0100, Suno Ano wrote: currently (January 2010) mainline is in development for the .33 release, .32 is stable and used by most Linux Distributions like for example Debian, Ubuntu, Suse, etc. From what it looks now Debian and Ubuntu are going into freeze for their next stable release in March 2010. Will there be an up-to-date OpenVZ kernel patch available by then? Debian is targeting to ship .32 with their next stable release called squeeze. In case OpenVZ will not be available on at least one of the major Linux distributions and its offsprings, no need to mention how horrid that would be ... http://lists.debian.org/debian-devel-announce/2009/10/msg3.html said OpenVZ will remain supported, but and http://lists.debian.org/debian-release/2009/08/msg00233.html had previously went unanswered and I don't see anything new at http://packages.debian.org/linux-image-2.6-openvz-686 I'm thinking the most usable compromise would be if someone volunteered to maintain the Debian packages of the actual kernel stable release 2.6.27 - where the meaning of stable more closely corresponds to the Debian stable release concept. For off-the-shelf usage, mainline releases can satisfy the same definition, but for corner cases it's doubtful because they tend to move too fast for people to track them reliably. I have to mention that Xen has a similar problem - there are XCI 2.6.27 patches which seem to be maintained, whereas it's doubtful anyone really wants to continue forward-porting the old branch to .32. Xen upstream do have an advanced paravirt_ops dom0 branch (it's much further along than LXC vs. OpenVZ, judging by the LXC description in this thread), but it would still be a regression compared to the old branch for some people who use some of those still-unimplemented features, so it's not a drop-in replacement yet. I'm Cc:ing Adrian Bunk - given that you initated the marking of .27 as the real stable, and Greg KH is still maintaining .27 upstream, I can't help but wonder if you might be willing to maintain those packages? :) Also Cc:'ing the debian-kernel mailing list. -- 2.

This is caused by the need for features like CONFIG_INOTIFY_USER, CONFIG_SIGNALFD and sysfs improvements so it cannot be resolved with trivial patches (I already did this to not require 2.6.27).
