Hello again This bug is fixed in latest OpenVZ RHEL6 kernel. Actually RHEL6 kernel is fully supported by OpenVZ team now, it has better performance and a few new features like vswap. Enjoy.

Here's how. 1. Get the latest kernel from either Download/kernel/rhel6-testing or Download/kernel/rhel6. You need vzkernel and vzkernel-devel packages only, with the -devel being optional. 2. Install fakeroot and alien: apt-get install alien fakeroot 3. Convert these two rpms to debs using alien. This is fakeroot alien --to-deb --scripts --keep-version vzkernel-*.rpm 4. Install debs as usual. Reboot. Enjoy. dpkg -i vzkernel*.deb On 02/14/2012 03:07 PM, Benjamin Henrion wrote: On Tue, Feb 14, 2012 at 11:48 AM, Benjamin Henrionb...@udev.org wrote: On Tue, Feb 14, 2012 at 11:29 AM, Benjamin Henrionb...@udev.org wrote: On Tue, Feb 14, 2012 at 11:26 AM, Benjamin Henrionb...@udev.org wrote: Hi, I am trying updatedb on a gentoo openvz container, the HN is a debian squeeze kernel.

Is this patch published somewhere in the GIT? It's published, but it's not in GIT. You can find this code in source rpms: http://download.openvz.org/kernel/branches/rhel6-2.6.32/042stab049.6/vzkernel-2.6.32-042stab049.6.src.rpm ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
Re: RE :RE: [Users] where are vm
Greetings, - Original Message - yes i find in vz/private/(id of your computer) but there this folder too i think vz/root/(id of your computer) but maybe there is more folder ... i find this folder too var/lib/vz/private/(id of your computer) so i don t really know if there are 3 folder or more or if they aren't all needed /vz/private/{ctid}/ is the permanent home for the container filesystem. /vz/root/{ctid}/ contents are there when the container is running. Debian likes to put things under /var/lib/vz/ and I think they just make /vz/ a symlink to it. A container = 1) It's config file (/etc/vz/conf/{ctid}.conf) and it's filesystem /vz/private/{ctid}. There is also a quota file in /var/vzquota/quota.{ctid}. These locations may vary from distro to distro as previously mentioned. Kir announced ploop 1.0 today... but the kernel and tools aren't available quite yet... but coming soon... for those who want to put a container on a disk image file. See this wiki page and the PDF of the presentation about ploop: http://wiki.openvz.org/Ploop ploop will be an addition and not replace what we have now... it'll be an option for those who want it.
