Zone clone using a snapshot

Create a new vnic;
[root] deckard:/root # dladm create-vnic -l etherstub0 vnic3
[root] deckard:/root # dladm show-vnic
LINK OVER SPEED MACADDRESS MACADDRTYPE VID
vnic2 etherstub0 0 2:8:20:ee:ac:53 random 0

Create a new zone;
[root] deckard:/root # zonecfg -z zone3 -f zone3cfg

Now create a clone of our original zone snapshot;
[root] deckard:/root # zoneadm -z zone3 clone -s tank/zones/zone1@SUNWzone1 zone1

Cloning a zone

[root] deckard:/root # zonecfg -z zone1 export -f /root/zone1cfg
[root] deckard:/root # cp zone1cfg zone2cfg
[root] deckard:/root # vi zone2cfg
Edit zone2cfg file - change the zonepath and physical net.
[root] deckard:/root # zonecfg -z zone2 -f zone2cfg
[root] deckard:/root # zoneadm list -cip

Zone creation

Just to save me looking it up next time, here's how I created a non-sparse zone.
(For a sparse zone omit the "remove inherit-pkg-dir" lines);

[root] deckard:/root # zonecfg -z zone1
zone1: No such zone configured
Use 'create' to begin configuring a new zone.
