Open Stack

when metadata server connecting problem.. please check below

- on network node(l3_agent running) ping to metadata_ip that specified by l3_agent.py
  if you using namespace run in router namespace
  ip netns exec qrouter-d7e9ec57-77c2-4046-aebf-d978ed4a4f83 ping metadata_ip

- meta traffic is transferred with DNAT from 169.254.169.254:80 to metadata_ip:8775

- on metadata server(nova_api server) check connection to vm's subnets such as 172.16.1.3
  openstack does not manage this routing. you manage this routing manually when tenant's subnet are private!
  i wrote little and dirty script manage this routing at external router:
