Comment 11 for bug 1541490

@Logan - I very much like the simplicity of that code change. But doesn't it break the mainline single NIC case? In other words, if the mainline case is for an instance to attach to a single network with a subnet with gateway IP and DHCP enabled, I think your change means that people using that case would also need to add a host route (0.0.0.0/0, <gateway IP>). (And that without that addition, an instance would not be able to route out of its NIC to the Internet.)
