The Solaris Plug-In includes a specific host set, a host search, and two host types for Solaris 10 zones.
Any host on which you want to install a zone must be a member of the global zone host set. To ensure this relationship, set the host type of the target host to com.sun.solaris#global_zone.
The global zones host search provides a search string that matches any host that is a global zone.
Any physical host on which you want to install a zone must have a host type of com.sun.solaris#global_zone.
When you install the Container component onto a global zone host, the provisioning software creates a host of type com.sun.solaris#local_zone.
