> OpenVZ provides the entire OS in a container.

Docker does that, too. Actually, I'm running docker containers as a fast and easy replacement for VirtualBox VMs.




Perhaps you could do this if you're on Linux, and booting into separate OS's that run off the Linux kernel. Or if you're using boot2docker. However, in neither case does Docker itself provide the kernel in the container.


What do you mean with that Docker does not provide the kernel itself? I did not mean Docker and OpenVZ are similar technology, they are exactly the same technology, just different toolset. You can only run Docker on linux (boot2docker simply runs a Linux VM), you use the kernel of the host os.
