You will need the following:
A supported SPARC or x86 system running the Oracle Solaris 11.3 release.
The default is the exclusive-IP type with an anet resource. For a shared-IP zone that requires network connectivity, you will need to provide one or more unique IPv4 addresses for each zone you want to create. You must also specify the physical interface.
A system running the Oracle Solaris 10 9/10 (or later released update) operating system that you want to migrate into a solaris10 container. An earlier update can be migrated with the appropriate kernel patch. You can generate your own images from existing systems. The process is described in Creating the Image for Directly Migrating Oracle Solaris 10 Systems Into Zones.
