Docker dropped LXC with version 0.6 or was it 1.0?  They have their own library that they use now.  Since I can't remember what version they switched, nor what version Red Hat has in RHEL7 (I'll leave it as an exercise for the reader)... perhaps the Docker currently shipping with RHEL7 still uses LXC?!?

The bulk of OpenVZ will never make it into the kernel although the Parallels kernel devs do try to integrate existing kernel features into OpenVZ (so the patch becomes smaller over time) as well as getting bits and pieces into the kernel or into userland (criu for example).

I wonder how much change OpenVZ will undergo in the port to the RHEL7 kernel... where considerable container building blocks are already part of the kernel.
