This howto shows how to detect OpenVZ support on the host and in the container.
#!/bin/bash
if [ -f /proc/user_beancounters ] ; then
envID=$(cat /proc/1/status |grep envID |cut -f 2)
if [ $envID -eq 0 ] ; then
echo "OpenVZ Host"
else
echo "OpenVZ Guest"
fi

# chkconfig libvirtd …This howto shows how to create an OpenVZ container on ploop
If you want all newly created containers to use ploop add this to /etc/vz/vz.conf
VE_LAYOUT=ploop
If you want to create only one container on ploop add '--layour ploop' to 'vzctl create' command
vzctl create CTID …This howto shows how to create an OpenVZ container with VENET interface.
Create the container
vzctl create 10221 --ostemplate centos-6-x86_64 --config vswap-1g
Configure the container
vzctl set 10221 --save --name server10221
vzctl set 10221 --save --onboot yes
vzctl set 10221 --save --hostname server10221.example.com
vzctl set 10221 --save --ipadd …
