Maybe this is rarely visible, but we are working hard on it for the last 
9 years.
I think it is correct to say Parallels/OpenVZ is the single biggest 
contributor to the
Linux Containers kernel code. Yes, we contributed more than Google, IBM 
or other
big guys. In terms of patches, it is well over 1500. The biggest 
features are:
  - net and PID namespaces,
  - CRIU kernel support (containers checkpoint/restore and more)
  - kernel memory accounting (still in progress).
  - (I guess I am missing something else)

We are working on the rest of it (and we hope the process will accelerate
with vzcore).

As to why such contribution is not very visible, my guess is people are 
not using
kernel directly, but relying on userspace tools such as lxc, vzctl and 
docker. So,
those tools are the only obvious component, with the Linux kernel doing 
its work
in background without much fanfares.
