Hi,
run a dhcp client on second instance, it should get added IP.
if you want to add port to existing instance then create port in
neutron:
neutron port-create --fixed-ip ip_address=1.2.3.4 vm_network_name
then get its ID and attach it to instance:
nova interface-attach --port-id 6eb03b5e-48fa-4c2b-8e3b-c56137086896 instance_name
it *can* be done directly during neutron port-create... but doesn't
work in icehouse;/ (port is added to neutron but permanently down in
nova) so it have to be done in 2 steps
