openvz install & use

Installation

x86_64 (2 cores)

CentOS5.1

cd /etc/yum.repos.d
wget http://download.openvz.org/openvz.repo
rpm --import http://download.openvz.org/RPM-GPG-Key-OpenVZ
yum install ovzkernel

(It will install x86 & x86_64, so del the i386, or it will lead to some errors.)

rpm -e ovzkernel-2.6.18-53.1.19.el5.028stab053.14.i686

(Change the /etc/sysctl.conf add or change the values)
