OpenVZ virtualization is at the level of OS (Operating System) based on a modified Linux kernel that allows a physical server to run multiple instances of so-called containers, virtual private server (VPS) or Virtual Environments (VE). The more general term used is the container. Container often analogized with chroot or jail, but the container is much better in terms of isolation, security, functionality, and management resources. OpenVZ is composed of a special Linux kernel and some user-level tools. OpenVZ is very portable, do not rely on the support of the VT on the CPU, so it is possible for a number of CPU type including x 86, x 86-64, IA-64, PowerPC and SPARC.
Virtualization-OS is very different with Virtualization Products-Hardware/Machine such as VMWare, VirtualBox, Xen and KVM. In the OpenVZ You can only do the Linux virtualization on Linux. Why use OpenVZ? Because of the relatively light, virtualization-OS offers a number of advantages than Virtualization-Hardware 1. Much more efficient 2. Allow more number of the container in a single server. 3. resource management parameters Offers a more complete details. 4. resource Management is dynamic so it does not need to restart the system container.
OpenVZ is able to achieve the performance, scalability, and density are better because there is a Linux kernel that runs on physical host where each container is only taking the resources necessary to execute the process/service therein, there is no need for the entire operating system. A basic-container can add 8-14 process on the host. OpenVZ is also able to handle advanced applications like Java multi-threaded applications. Other advantages of OpenVZ is offering a variety of dynamic resources management parameters include: memory usage, number of processes, the level of CPU usage, disk space usage, and others all of which it can be change while the container remains running. OpenVZ also supports disk space quota and the quota of disk space for user/group in the container.
