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.
OpenVZ is not compatible with the xfs file system, so please make sure that you have built the system with ext4 file system
