"Faster than virtualization, but harder to implement, containers are a promising security technology for Linux. Watch the 2.6.24 kernel for experimental support for creating and managing containers."

A Solaris Container is different than a Zone, a Container is used to limit resources used by a specific process or group of processes. For example, if I wanted to limit the number of CPU's "seen" by Oracle for licensing reasons, I would use a Container to accomplish this. Read the folloing PDF's from Oracle and Sun for details:

The Computerworld article is talking about making Containers available for Linux, which is an important step in making Linux compete at the same level as Solaris, AIX and HP-UX in the Enterprise arena. From the article:
"Containers" are a form of lightweight virtualization as represented by projects like OpenVZ. While virtualization creates a new virtual machine upon which the guest system runs, containers implementations work by making walls around groups of processes. The result is that, while virtualized guests each run their own kernel (and can run different operating systems than the host), containerized systems all run on the host's kernel."
