#  Create and start a container 
# To create and start a container, run the following commands:
# 
# [host-node]# vzctl create CTID --ostemplate osname
# [host-node]# vzctl set CTID --ipadd a.b.c.d --save
# [host-node]# vzctl set CTID --nameserver a.b.c.d --save
# [host-node]# vzctl start CTID
#

vzctl create 1 --ostemplate centos-5-x86
vzctl set 1 --ipadd 10.0.51.254 --save
vzctl set  1 --nameserver 192.168.1.20 --save
vzctl start 1


# Here CTID is the numeric ID for the container; osname is the name of the OS template for the container, and a.b.c.d is the IP address to be assigned to the container.
# Your freshly-created container should be up and running now; you can see its processes:
# 
[host-node]# vzctl exec CTID ps ax
# 
# Enter to and exit from the container
# 
# To enter container give the following command:
# 
[host-node]# vzctl enter CTID
# entered into container CTID
# [container]#
# 
# To exit from container, just type exit and press Enter:
# 
[container]# exit
# exited from container VEID
# [host-node]#
# 
# Stop and destroy the container
# 
# To stop container:
# 
[host-node]# vzctl stop CTID
# Stopping container ...
# Container was stopped
# Container is unmounted
# 
# And to destroy container:
# 
[host-node]# vzctl destroy CTID
# Destroying container private area: /vz/private/CTID
