To create such a zone involves letting the system pick default settings, which includes the loopback filesystem (lofs) read only mounts that share most of the OS. The following commands were used

Quote:

# zonecfg -z small-zone
small-zone: No such zone configured
Use 'create' to begin configuring a new zone.

zonecfg:small-zone> add net
zonecfg:small-zone:net> set address=192.168.2.101

Then we can install the ZONE.
