1. Shtidown the non-global zone (in our case zone01).

# zlogin zone01 shutdown

2. Set the hostid of your choice using zonecfg command.

# zonecfg -z zone01
zonecfg:zone01> set hostid=80f0c086        (HOSTID of your choice)
zonecfg:zone01> exit

3. Boot the zone for the changes to take effect.

# zoneadm -z zone01 boot
