Hi,
I am using the new debian release (squeeze) and the kernel 2.6.32-5-openvz-amd64.

When i create a container, it is not possible to limit the number of cpu.

I use CPUS et CPULIMIT parameters and with HTOP command i can see all the cpu offered by the hardware.

Is there anybody who know if it is possible to limit this ressource ? And which kernel has to be used on Debian to limit it ?

thanks.
BERTRAND

Try this one:

wiki.openvz.org/Download/kernel/rhel6/042test007.1

Recompile it. Should work with Debian 6.

It is still testing kernel. If you are going to use new RAM limits with physpages and swappages set - there is a bug: bugzilla.openvz.org/show_bug.cgi?id=1749 and server may stuck at cpu software lock.
Anyway - this kernel has a cpu limit future so you will be able to limit your cpu resources.

Hi,

I try to compil it using this tutorial :
wiki.openvz.org/Compiling_the_OpenVZ_kernel_(the_Debian_way)

Everything works fine, but i did'nt patch the kernel.

I download the source from squeeze repositories (aptitude install kernel-package linux-source-2.6.32)

I use this config wiki.openvz.org/Download/kernel/rhel6/042test008.1
config-2.6.32-042test008.1.x86_64

I download this patch : patch-042test008.1-combined.gz on the same page

I extract and make ./patch-042test008.1-combined

And ...

When i make config, i id not have a line with openvz. So i guest the kernel was not patching.

Could you explain how to compil, or give me some informations to
fix this problem.
