[openstack-dev] [Nova] Why Nova should fail to boot if there are only one private network and one public network ?

I filed a bug [1] a while ago about the impact of a review [2] which now 
prevents Nova to boot instances if there are two available networks 
within Neutron.
As a side effect, users now need to pass the nic ID on the nova boot 
command even for simple setups with only one private network (and 
subnet) and one public net (with one subnet)

IMHO, we should segragate public from private networks and only allow to 
count private networks.
This would have at least the benefit for devstack users and begineers to 
not wonder why it should give a nic hint for properly boot his VM.

Thoughts, before I'm submitting a review ?
