Hi !

When I run the following command seems to have no effect on the CT :

vzctl set 860 --cpus 1 --save

then i run :

vzctl exec 860 cat /proc/cpuinfo

this is what I got :

Hi,

you need a stable OpenVZ Kernel, the 2.6.18 RHEL branch, not a devel one ... see http://bugzilla.openvz.org/show_bug.cgi?id=909

Bye,
Thorsten

Thank for your answer...

Do you know what is the stable kernel for Debian Lenny x64 ? do you think if I make a apt-get upgrade that will solve this problem ?

Thx.

I'm looking for the "easy debian way" to solve this problem without compile a new kernel, can somebody help me please ?

Thanks.
