How to Install OpenVZ 7 on CentOS 7
This is a complete guide to converting a CentOS 7 server to a OpenVZ host server.
The recommended pattern to install OpenVZ is to use the ISO and install it on the bare metal.
However, that isn't always possible, so in this tutorial, we'll explain how to install OpenVZ on CentOS.
You'll need a server with CentOS 7 x86_64 installed.
I'll be using CentOS 7.9.
