[https://src.openvz.org/projects/OVZ/repos/criu/branches The CRIU fork ]
Because not all features implemented in Open Virtuozzo are merged into vanilla kernel yet, it's been adopted to create a fork of CRIU with Virtuozzo specific patched on top of vanilla instance. The [https://src.openvz.org/scm/ovz/criu.git CRIU-VZ] is open project of course with the following branches:
[https://src.openvz.org/projects/OVZ/repos/p.haul/browse The P.Haul fork ]
* '''master''' — is a copy of vanilla master branch
* '''vz7-rtm''' — Virtuozzo 7 criu instance
* '''vz7-u1''' — current stable branch of Virtuozzo 7 with patches which will come into next Virtuozzo update
While vanilla CRIU is a fast pacing project the Virtuozzo instance is usually slightly behind. In particular currently v2.5 is used as a stable base.
