If you are using neutron's nova metadata agent, it runs a process per
network, then uses a domain socket to escape the network namespace and
communicate with a parent that talks to nova.

If you are using nova-networking, its handled by an iptables DNAT rule
to take incoming requests and forward them to the actual API IP
