Basic operations in OpenVZ environment

This article assumes you have already installed OpenVZ and prepared the OS template cache(s). If not, follow the links to perform the steps needed.

To create and start a VE, run the following commands:

[host-node]# vzctl create VEID --ostemplate osname
[host-node]# vzctl set VEID --ipadd a.b.c.d --save
[host-node]# vzctl start VEID

Here VEID is the numeric ID for the VE; osname is the name of the OS template for the VE, and a.b.c.d is the IP address to be assigned to the VE.

Example:

[host-node]# vzctl create 101 --ostemplate fedora-core-5-minimal
[host-node]# vzctl set 101 --ipadd 10.1.2.3 --save
[host-node]# vzctl start 101

Your freshly-created VE should be up and running now; you can see its processes:

[host-node]# vzctl exec VEID ps ax

See the vzctl(8) man page for more information.
