'''OpenVZ''' is the basis of [[Virtuozzo]], a project that combines the following container virtualization technologies solution offered by [http://www.virtuozzo.com/ Virtuozzo] company. Virtuozzo is optimized for Linux:hosters and offers hypervisor (VMs in addition to containers), [[Virtuozzo_Storage|distributed cloud storage]], dedicated support, management tools, and easy installation.

* [[Download/kernel|Virtuozzo kernel]], a Linux kernel with patches that implements OpenVZ kernel functionality.* Management utilities, such as [[Download/vzctl|vzctl]], for managing container life cycle.* [http://criu.org/ Checkpoint/Restore In Userspace], or CRIU, is a software tool for Linux that enables you to freeze a running application (or a part of it) == Installation and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at.* [[Ploop]] is a disk loopback block device, not unlike loop but with many features like dynamic resize, snapshots, backups etc. The main idea is to put container filesystem in a file.* [http://criu.org/P.Haul P.Haul] is the project on top of CRIU that implements the live migration usage scenario.* [[LibCT]] is a container management library that provides a convenient API for front-end programs for managing the entire container life cycle.* [[VCMMD]] is a Virtuozzo Containers memory management daemon. Upstream technology to manage containers memory.OpenVZ is free open source software, available under GNU GPL or compatible licenses.==

OpenVZ is easy to install if you already have Linux installed on your machine. See [[Virtuozzoquick installation]] is for installation info. Alternatively, you can try a [[Download live CD|live CD]] to test drive the technology without a Linux distribution based on OpenVZ componentsneed to install anything.
