We have just released a new RHEL6-based kernel, 042test005. It is shaping up pretty good — as you can see from the changelog, it's not just bug fixes but also performance improvements. If you haven't tried it yet, I suggest to do it today! Do not postpone this until 2011 — after all, this is what will become the next stable OpenVZ kernel.

RHEL6 kernel needs an appropriate (i.e. recent) Linux distribution. If you don't want latest Fedora releases, can't afford RHEL6, and tired of waiting for CentOS 6, I suggest you go with Scientific Linux 6 (SL6). This is yet another RHEL6 clone developed and used by CERN, Fermilabs and other similar institutions.

While SL6 is still at its infancy (they have recently released alpha 3 and plan to release beta 1 at Jan 7 2011), it it worth trying since it's based on a very stable set of sources from RHEL6. Repositories and stuff are available from http://ftp.scientificlinux.org/linux/scientific/6rolling/

Re: put_fs_struct
How did you found it?
This trash is defined under #ifdef CONFIG_MM_OWNER, which is not compatible with our kernel =)

root@hostname:/usr/src/linux-2.6.32# cat ../patch-042test005 | grep put_fs_struct
+EXPORT_SYMBOL_GPL(put_fs_struct);

It is in your patchset. I am using CONFIG_MM_OWNER because it is needed by dm-ioband cgroup patchset. I am going to use it and make few test with your great kernel.
Blkio throttle V1 patchset by Vivek working great but doing kernel panic on scsci subsystem randomly... (and only for software raid arrays... ;))

Would be really great if virtuozzo team will merge and open the iolimit functionality from virtuozzo kernel to openvz.
That's why I am working on it to have the iolimit throttle for openvz.
