I'm not convinced that's needed.  It certainly isn't needed when
creating a zone from scratch, and the Solaris 11 docs don't state that
it is required.  At any rate it doesn't make a difference.

Here's a step-by-step process.  If people are interested in trying to
reproduce this (and of course fix it), follow these steps:

1) Create a vnic for an example zone

root at omnios:~# dladm create-vnic -l bge0 c1

2) Create the zone

root at omnios:~# zonecfg -z clone1
clone1: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:clone1> create
zonecfg:clone1> set zonepath=/zones/clone1
zonecfg:clone1> set brand=ipkg
zonecfg:clone1> set autoboot=true
zonecfg:clone1> set limitpriv=default,dtrace_proc,dtrace_user
zonecfg:clone1> set ip-type=exclusive
zonecfg:clone1> add net
zonecfg:clone1:net> set physical=c1
zonecfg:clone1:net> end
zonecfg:clone1> commit
zonecfg:clone1> verify
zonecfg:clone1> exit

3) Install the zone

root at omnios:~# zoneadm -z clone1 install
A ZFS file system has been created for this zone.
   Publisher: Using omnios (http://pkg.omniti.com/omnios/release/ ).
       Image: Preparing at /zones/clone1/root.
       Cache: Using /var/pkg/publisher.
Sanity Check: Looking for 'entire' incorporation.
  Installing: Packages (output follows)
           Packages to install: 388
       Create boot environment:  No
Create backup boot environment:  No
            Services to change:   4

        Note: Man pages can be obtained by installing pkg:/system/manual
 Postinstall: Copying SMF seed repository ... done.
        Done: Installation completed in 178.089 seconds.

  Next Steps: Boot the zone, then log into the zone console (zlogin -C)
              to complete the configuration process.

4) Configure the zone

root at omnios:~# zoneadm -z clone1 boot
root at omnios:~# zlogin clone1
[Connected to zone 'clone1' pts/4]
OmniOS 5.11     omnios-33fdde4  2012.10.04
root at clone1:~# ipadm create-addr -T static -a 10.1.1.151/24
c1/v4address                                                  $
root at clone1:~# cp /etc/nsswitch.dns /etc/nsswitch.conf
root at clone1:~# echo "nameserver 8.8.8.8" > /etc/resolv.conf
root at clone1:~# route -p add default 10.1.1.1
add net default: gateway 10.1.1.1
root at clone1:~# ipadm show-addr
ADDROBJ           TYPE     STATE        ADDR

lo0/v6            static   ok           ::1/128
root at clone1:~# ping 10.1.1.1
10.1.1.1 is alive
root at clone1:~# exit
logout

workstation> ping 10.1.1.151

5) Halt clone1

root at omnios:~# zoneadm -z clone1 halt

6) Create a new vnic for the machine we're going to create by cloning

root at omnios:~# dladm create-vnic -l bge0 c2

7) Create the zone config for the new machine

root at omnios:~# zonecfg -z clone1 export | sed
's/clone1/clone2/g;s/c1/c2/g' | tee /tmp/c2.config
     $
create -b
set zonepath=/zones/clone2
set brand=ipkg
set autoboot=true
set limitpriv=default,dtrace_proc,dtrace_user
set ip-type=exclusive
add net
set physical=c2
end

8) Create the new zone

root at omnios:~# zonecfg -z clone2 -f /tmp/c2.config

9) Clone the first machine to the second machine

root at omnios:~# zoneadm -z clone2 clone clone1

root at omnios:~# zoneadm list -vc | grep clone
   - clone1           installed  /zones/clone1                  ipkg     excl
   - clone2           installed  /zones/clone2                  ipkg     excl

10) Boot the new machine

root at omnios:~# zoneadm -z clone2 boot

11) Attempt to configure networking on clone2

root at clone2:~# dladm show-link
LINK        CLASS     MTU    STATE    BRIDGE     OVER
c2          vnic      1500   up       --         ?

root at clone2:~# ipadm create-if c2
ipadm: Could not create c2 : Object not found

root at clone2:~# ipadm show-if
IFNAME     STATE    CURRENT      PERSISTENT
lo0        ok       -m-v------46 ---

root at clone2:~# ipadm create-addr -T static -a 10.1.1.152/24 c2/v4address
ipadm: Could not create address: Object not found
