I was lucky enough to get some time to tell Rick Ramsay about Kernel Zones, unfortunately it was only 5 minutes You can see the result here (go on you know you want to):
You can also get started with Oracle Solaris Kernel Zones with the help of this howto guide.

From time to time as the product manager for Oracle Solaris Virtualization I get asked by customers which virtualization technology they should choose. This is probably because of two main reasons.
- Choice: Oracle Solaris provides a choice of virtualization technologies so you can tailor your virtual infrastructure to best fit your application, not to have force (and hence compromise) your application to fit a single option
- No way back: There is the perception, once you make your choice if you get it wrong there is no way back (or a very difficult way back), so it is really important to make the right choice
Understandably there is occasionally a lot of angst around this decision but, as always, with Oracle Solaris there is good news. First the choice isn't as complex as it first seems and below is a diagram that can help you get a feel for that choice. We now have many many customers that are discovering that the combination of Oracle Solaris Zones inside OVM Server for SPARC instances (Logical Domains) gives them the best of both worlds.
Second with Unified Archives in Oracle Solaris 11.2 you always have a way back. With a Unified Archive you can move from a Native Zone to a Kernel Zone to a Logical Domain to Bare Metal and any and all combinations in-between. You can test which is the best type of virtualization for your applications and infrastructure and if you don't like it change to another type in a few minutes.

Not using Oracle Solaris Zones? I have to ask, why not? With massive adoption on Oracle Solaris and the additions to Oracle Solaris Zones in Oracle Solaris 11 the reasons to place your applications inside a zone just become more and more compelling.
Now, there is one less reason not to move. It's there already as part of the product in Oracle Solaris 11, but for those of you with Oracle Solaris 10 systems you can now get access to the Oracle Solaris Zones Preflight System Checker on OTN (scroll down a bit from the link).
You can now evaluate an Oracle Solaris 10 host for migration into an Oracle Solaris Zone. The following migration scenarios are supported:
- Migration to an Oracle Solaris Zone on an Oracle Solaris 10 Host.
- Migration to an Oracle Solaris Zone on an Oracle Solaris 11 Host.
And gives you the following capabilities:
- Analysis of the Oracle Solaris configuration, including networking, storage, and Oracle Solaris Operating system features in use.
- Analysis of application binaries.
- Analysis of running applications.
- Generation of a template Oracle Solaris Zone configuration to use on the target host.
