The OpenVZ/Virtuozzo developers from Parallels have been working on Linux container technologies since 1999. What was originally a separate patchset is now mostly merged into the upstream Linux kernel, enabling the way for projects like LXC and Docker. In the mean time, the OpenVZ/Virtuozzo Linux kernel is still one step ahead of the vanilla kernel when it comes to containers.

The talk will provide details about recent efforts towards Docker and Virtuozzo interoperability. This development is twofold. The first goal is to run Docker inside an OpenVZ container and the second goal is to use the proven OpenVZ kernel as a backend for Docker (via libcontainer).
