OpenVZ is a free open source software that provides container-based virtualization solution for Linux. OpenVZ 7 is the latest version of OpenVZ out there and it comes with Red Hat Enterprise Linux 3.10 kernel. This post is all about how to setup OpenVZ 7 on CentOS 7.x servers.
One Kernel, Many VM’s
OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Here, all the Linux containers share a single Kernel. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.
