1. Add the OpenVZ repo.

cd /etc/yum.repos.d
wget http://download.openvz.org/openvz.repo
yum -y install ovzkernel

2. Adjust the sysctl.conf

vi /etc/sysctl.conf 
# Controls IP packet forwarding
net.ipv4.ip_forward = 1 
# Controls source route verification
net.ipv4.conf.default.rp_filter = 1
# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 1 
net.ipv4.conf.default.proxy_arp = 0
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
# Enables source route verification
net.ipv4.conf.all.rp_filter = 1
sysctl -p
shutdown -r now
uname -r

3. Install openvz tools.
