Containing Oracle Linux

When I originally read this article on the Linux Containers project I was surprised this virtualization technology is being proposed for use on Oracle Linux.  Today I re-read the article, and saw this note emphasized:

Note: Linux Containers on Oracle Linux 6 with the Unbreakable Enterprise Kernel Release 2 (2.6.39) are still marked as Technology Preview - their use is only recommended for testing and evaluation purposes.

I think using this to test and maybe offset some costs is a great idea, but then you're getting outside the prospect of having the same approved and supportable configuration in your PROD, QA and DEV instances.
