wget -P /etc/yum.repos.d/ http://ftp.openvz.org/openvz.repo导入OpenVZ 的GPG key用于 标记RPM包
rpm --import http://ftp.openvz.org/RPM-GPG-Key-OpenVZ安装OpenVZ的Kernel
Limited OpenVZ functionality is supported when you run a recent 3.x kernel (check vzctl for upstream kernel, so OpenVZ kernel installation is optional but still recommended.
# yum install vzkernel

Complete!系统配置
配置完成之前不要重启OpenVZ kernel
配置sysctl.conf
There are a number of kernel parameters that should be set for OpenVZ to work correctly. These parameters are stored in /etc/sysctl.conf file. Here are the relevant portions of the file; please edit accordingly.
vi /etc/sysctl.conf
# On Hardware Node we generally need
# packet forwarding enabled and proxy arp disabled
net.ipv4.ip_forward = 1
net.ipv6.conf.default.forwarding = 1
net.ipv6.conf.all.forwarding = 1
net.ipv4.conf.default.proxy_arp = 0
# Enables source route verification
net.ipv4.conf.all.rp_filter = 1
# Enables the magic-sysrq key
kernel.sysrq = 1
# We do not want all our interfaces to send redirects
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0设置防火墙为disabled
vi /etc/sysconfig/selinux
SELINUX=disabled安装Tools
OpenVZ needs some user-level tools installed:
# yum install vzctl vzquota ploop

Adding the following option to /etc/modprobe.d/openvz.conf:
options nf_conntrack ip_conntrack_disable_ve0=0
This change will take effect only after the next reboot.
NOTE: if you need to change this setting, edit /etc/modprobe.d/openvz.conf
now. DO NOT REMOVE the line, or it will be re-added!

reboot下载OS templates
An OS template is a Linux distribution installed into a container and then packed into a gzipped tarball. Using such a cache, a new container can be created in a minute.
镜像下载地址： https://download.openvz.org/template/precreated/
所有镜像地址： https://openvz.org/Download_mirrors
Put those tarballs as-is (no unpacking needed) to the /vz/template/cache/ directory.
