OpenVZ это проект, объединяющий технологии контейнерной виртуализации для is a project that combines the following container virtualization technologies for Linux:

*'''Virtuozzo kernel''' is a Linux kernel with patches that implements OpenVZ kernel functionality.

*'''Management utilities''' , such as vzctl, to manage container life cycle.

*'''Checkpoint/Restore In Userspace''', or CRIU (pronounced kree-oo, IPA: /krɪʊ/, Russian: криу), is a software tool for Linux operating system. Using this tool, you can freeze a running application (or 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. The distinctive feature of the CRIU project is that it is mainly implemented in user space. Docker and LXC uses CRIU to be able to migrate containers between servers. '''P.Haul''' is the project on top of CRIU implementing live migration usage scenario. '''LibCT''' is a containers management library which provides convenient API for frontend programs to rule a container during its whole lifetime.
