[OpenIndiana-discuss] network errors

zonecfg -z gls3  info
zonename: gl3
zonepath: /zones/gls3
brand: ipkg
autoboot: true

I have multiple zones that share nics over net0, net1 and net2. 
I come from the dark lands of solaris 10 and never used crossbow or vnics
because it was never needed. 

Today I tried to use a vnic setup for a zone to test with it, but Oi
documentation is very limited and new solaris11 documentation uses
instructions that are not incorporated in OI. 
"Ipadm create-ip" is for example a solaris 11 instruction which is not
available in OI. There is a ipadm create-if in OI, but I don't know if it is
the same.  

When I finally had a zone running with a vnic it couldn't reach the network,
so I moved the complete webserver to solaris 11 and there it runs without
problems with the same ip-address.

just to start, are these ip-type=shared, or ip-type=exclusive?

If they are shared, can you show us a limited "net" only section of your
svccfg -z <zone> info ?

Is there any reason that you are using separate cards for each zone, and not
just virtualizing the cards?
