Branded zones are available beginning with the Solaris 10 8/07 release.
The Branded zone (BrandZ) provides the framework to create non-global branded zones that contain non-native operating environments used for running applications.
Every zone is configured with an associated zone. The default is the native brand, Solaris. A branded zone will support exactly one brand of non-native binary, which means that a branded zone provides a single operating environment.
Note :
1. Cannot run Solaris applications inside an lx zone. However, the lx zone enables us to use the Solaris system to develop[, test, and deploy Linux applications. For eg, we can place a Linux application in an lz zone and analyze it using Solaris tools run from the global zone.
2. We can change the brand of a zone in the configured state. Once a branded zone has been installed, that brand cannot be changed or moved.
3. The system must be either x64 or x86 based.
4. The lx (Linux) brand supports only the whole root model, so each installed zone will have its own copy of every file.
5. There are no limits on how much disk space can be consumed by a zone. The global administrator is responsible for space restriction.
6. Currently lx brand installer supports only Red Hat Enterprise Linux 3.x and the equivalent CentOS distributions.

7. Regarding, assigning the name to be branded zone, rules is similar to a non-global zone.

3. Configuring BrandZ zone:
bash-3.00# mkdir -m 700 /export/home/linux_brandz
bash-3.00# zonecfg -z linux_brandz
linux_brandz: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:linux_brandz> create -t SUNWlx
zonecfg:linux_brandz> set zonepath=/export/home/linux_brandz
zonecfg:linux_brandz> add net
zonecfg:linux_brandz:net> set physical=e1000g0
zonecfg:linux_brandz:net> set address=100.0.0.123
zonecfg:linux_brandz:net> end
zonecfg:linux_brandz> commit
zonecfg:linux_brandz> exit
bash-3.00# zoneadm -z linux_brandz install -d /Desktop/centos_fs_image.tar.bz2
where
-d = specifies the path of the non-native OS tarball/image.
Installing zone 'linux_brandz' at root directory '/export/home/linux_brandz'
