I can't run a curl against the metadata server either.

The VMs typically shouldn't have a 169 route; also you can't ping the
metadata server since its usually DNAT on the port (80) rather than a fully
accessible IP address.

  The only place I can ping is on the Region server which is where the 169
  address sits.

  Few troubleshooting steps (assuming neutron's metadata agent):
  1. Check through VM's console.log whether VMs are acquiring DHCP Ip
  address
  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.
  3. If yes to #1, restart neutron-metadata-agent

  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
  address/port.
