CT0

In OpenVZ, you have multiple CTs, 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 containers. From CT0, all the containers' processes, files, etc. are accessible. From CT0, you manage the hardware, install a new kernel, etc.
