<!--<translate>--><!--T:1-->'''VirtuozzoOpenVZ 7''' is [http://www.odin.com/ Odin] a virtualization and automation solution built on top of OpenVZcomponents. Virtuozzo OpenVZ 7 provides improvements and additional functionality in the areas of density, management tools, recovery, and other areasetc. Specific benefits of Virtuozzo OpenVZ compared to OpenVZ other virtualization solutions can be found in [[Comparison|this article]]. Virtuozzo built on top of OpenVZ technologies but provides extended number of functionality, enhanced amount of services and support.
<!--T:2-->
OpenVZ is a small open-source part of [https://www.virtuozzo.com/products/vz7.html Virtuozzo 7 infrastructure] which provides necessary features, services, and support for medium and large businesses. Most notable features of Virtuozzo are reliable and fast [[Virtuozzo_Storage|software-defined storage]], automated [https://docs.virtuozzo.com/virtuozzo_7_users_guide/managing-virtual-machines-and-containers/managing-virtual-machine-and-container-backups.html backups], higher [https://docs.virtuozzo.com/virtuozzo_7_command_line_reference/managing-containers/supplementary-tools.html density of containers], live patching for kernel by [https://docs.virtuozzo.com/virtuozzo_infrastructure_platform_admins_cmd_guide/advanced-tasks/updating-with-readykernel.html ReadyKernel], timely [https://docs.virtuozzo.com/virtuozzo_7_users_guide/keeping-your-system-up-to-date/updating-virtuozzo.html updates] and [https://www.virtuozzo.com/support/all-products.html 24x7 support].
== Components ==<!--T:3-->
<!--T:4-->
OpenVZ consists from open components and includes:
<!--T:5-->* [[Download/kernel/rhel7|RHEL7 kernel]], RHEL7-based kernel, a Linux kernel with patches that implements OpenVZ kernel functionality.* Management utilities, such as [[Download/vzctlCRIU|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) 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.
* [[QEMU]]/KVM
* [http://criu.org/P.Haul [P.Haul]] is the project on top of CRIU that imple- ments 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.
* [[LibVirt]] - API to manage virtual machines as well as containers
* [https://src.openvz.org/projects/OVZ/repos/libprlsdk/browse [Libprlsdk|Virtuozzo SDK] ] is our own API to manage virtual machines and containers with Python bindings.* and [[:Category:Sub-projects | other components]]
