Subject Re: networks and isolation/broadcast

That's just it. The isolation type *is* provided when creating
physical network. If I create a physical network with isolation type
'VXLAN', and then add traffic type of 'Public', it doesn't obey it.
There's physical_networks and networks, when the zone is created, an
entry goes in network that is Public/Vlan, hardcoded. The Public
traffic type uses this, regardless of what the physical_network its
being added to says. So if we updated the the public network table row
with the correct isolation method for that physical network we are
adding traffic type to when we add the public traffic type, that would
work. It's worth noting that a zone can only have one physical network
with traffic type of public.
