In OpenVZ, you have multiple [[VECT]]s, as well as the '''host system''' itself, which is otherwise known as '''CT0''' or '''VE0'''. In other words, CT0 means the server itself.

From CT0, you can use [[vzctl]] and other tools to manage [[container]]s. From CT0, all the containers' processes, files, etc. are accessible. From VE0CT0, you manage the hardware, install a new kernel, etc.
