Libcontainer VS. LXC driver

Question

What are main differences between these Docker drivers? Why is libcontainer better than LXC driver? Why should we use libcontainer, which are its benefits on practical way?

Answer 1

Libcontainer is built into the code of Docker and clearly their favored choice.

Using a built-in library reduces dependencies and other moving parts, so it should be faster and can be considered more stable.

All is explained in more detail in the Docker Blog.
