How to create a Solaris local zone with an exclusive NIC?
I'm trying to migrate a Solaris 10 flar archive from a Sun M3000 to a T4-1. When I first created the zone I followed the Oracle instructions here: Transitioning an Oracle Solaris 10 Instance to an Oracle Solaris 11 System - Transitioning From Oracle Solaris 10 to Oracle Solaris 11 That worked OK, in the sense that I was able to boot the zone and access it via ssh and vncviewer. However, I did not realize that without an exclusive NIC, my zone would not be able to do DHCP which means the Sun Ray server would not work, and I have to have that.

Now the T4-1 has four gigabit NICS, labeled on the back net0 - net3. I had one cable connected to net0. So I added a second cable from a free port on my switch to net1 and tried to reconfigure my zone to use it instead of net0. That's when all hell broke loose. I can still talk to the global zone over my LAN but my local zone will no longer even boot.

Here's a few possibly relevant pieces:
Code:
root@hemlock:/# dladm
LINK                CLASS     MTU    STATE    OVER
ldoms-vsw0.vport0   vnic      1500   up       net0
ldoms-vsw0.vport1   vnic      1500   up       net0
net0                phys      1500   up       --
net1                phys      1500   up       --
net2                phys      1500   unknown  --
net3                phys      1500   unknown  --
net4                phys      1500   up       --

sp-phys0            phys      1500   up       --

Attempting to turn on net1 and boot the zone, I get this:
Code:
root@hemlock:/# ifconfig net1 plumb
ifconfig: cannot plumb net1: Interface already exists
root@hemlock:/# ifconfig net1 dhcp start
root@hemlock:/# zoneadm -z s10zone install -u -a /rpool/s10archive/s10.flar
zoneadm: zone s10zone: WARNING: Skipping network interface: interface 'net1' is used in the global zone.
ERROR: 
Zone rpool data set rpool/zones/s10zone/rpool already exists. Aborting the operation
zoneadm: zone 's10zone': ERROR: installation failed: zone switching to configured state
root@hemlock:/#

It doesn't like the global zone having net1? OK, so we try
Code:
root@hemlock:/# ifconfig net1 unplumb
root@hemlock:/# zoneadm -z s10zone install -u -a /rpool/s10archive/s10.flar
ERROR: 
Zone rpool data set rpool/zones/s10zone/rpool already exists. Aborting the operation
zoneadm: zone 's10zone': ERROR: installation failed: zone switching to configured state
root@hemlock:/#

My zone is already configured? So where is it?
Code:
root@hemlock:/# zoneadm list
global
root@hemlock:/#

Rather than continuing thrashing about in the dark, I figure it's time to ask for help. I freely admit to having no clue what I'm doing.
