Subject Re: 2 Network Interfaces on Instance

I believe achieving network isolation by segmenting physical networks is
not working currently. Though steps mentioned by Geoff are valid, and
functionality does exist, but there is artificial limitation that is
forcing VLAN to be passed while creating networks. There is bug [1] opened
for 4.1 release.
