One of the new features in Ops Center 12.3 is support for Oracle Solaris kernel zones. I wanted to talk a bit about this, because there are some caveats, and a new document to help you with using this type of zone.
Kernel zones differ from other zones in that they have a separate kernel and OS from the global zone, making them more independent. In Ops Center 12.3, you can discover and manage kernel zones. However, you can't migrate them, put them in a server pool, or change their configuration through the user interface.
We put together a how-to that explains how you can discover existing kernel zones in your environment. You can also take a look at the What's New doc for more information about what's changed in 12.3.
