Cloning enables you to copy an existing configured and installed zone on your system to a new zone on the same system. The cloned zone includes any customizations of the existing zone. For example, added packages, modified zone resources, and file modifications on the source zone will appear in each cloned zone. Cloning a zone is an efficient way to add additional zones with a similar customized zone configuration.
You can clone a kernel zone in the following ways:
Use the zoneadm clone command if you need to clone a small number of zones. See Example 2–4.
Use a Unified Archive file if you need to clone multiple zones for a large deployment, such as in a data center environment. See Example 2–5.
After a kernel zone is cloned, you can boot and log in to the new zone.Example 2-4 Cloning a Kernel Zone by Using the zoneadm clone Command.
This example demonstrates how to clone the kernel zone kzone1 to the kernel zone kzone2 on the host global. For a step-by-step procedure, see Cloning a Non-Global Zone on the Same System in Creating and Using Oracle Solaris Zones .

The following example demonstrates cloning and deploying the kernel zone kzone1 by using the archiveadm command. A Unified Archive is created for the kernel zone kzone1. The archive info is verified and the kernel zone kzone2 is cloned with the modified zone configuration from kzone1. For a step-by-step procedure, please see Using Unified Archives for System Recovery and Cloning in Oracle Solaris 11.2 .
