Basic OpenVZ commands

To set up a VPS from the default CentOS 5 template you have to use the below command:

vzctl create 101 –ostemplate centos-5-x86 –config basic

The 101 must be a uniqe ID – each virtual machine must have its own unique ID.
If you want to have the vm started at boot, run

vzctl set 101 –onboot yes –save

To set a hostname and IP address for the vm, run:

vzctl set 101 –hostname test.example.com –save

vzctl set 101 –ipadd 192.168.1.101 –save

To start the vm

vzctl start 101

To set a root password for the vm, execute

vzctl exec 101 passwd

To login into vm

vzctl enter 101

To leave the vm’s console, type

exit

To stop a vm, run

vzctl stop 101

To restart a vm, run

vzctl restart 101

To delete a vm from the hard drive (it must be stopped before you can do this), run

vzctl destroy 101

To get a list of your vms and their statuses, run

vzlist -a

To find out about the resources allocated to a vm, run

vzctl exec 101 cat /proc/user_beancounters

Command to check the load of all VPS from main server node.
