<!--<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, etc. Specific benefits of Virtuozzo OpenVZ compared to OpenVZ other virtualization solutions can be found in [[Comparison|this article]]. Virtuozzo is built on top of OpenVZ technologies but provides more features, 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]]
