Few troubleshooting steps (assuming neutron's metadata agent):<br>
1. Check through VM's console.log whether VMs are acquiring DHCP Ip address<br>
2. If not, check all the bridges (on both controller and compute) up and running s (br-int or br-tun), generally on reboot some of these bridges do not come up. <br>
3. If yes to #1, restart neutron-metadata-agent<br>

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.<br>
<br>
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 address/port.<br>
