Public bug reported:
In my mitaka environment, there are five nodes here, including
controller, network1, network2, computer1, computer2 node. I start
l3-agents with dvr_snat mode in all network and compute nodes, and it
works well for most neutron services unless the metadata proxy service.
Then enable metadata-proxy true. When I run command "curl
http://169.254.169.254"; in an instance booting from cirros, it returns
"curl: couldn't connect to host" and the instance can't get metadata in
its first booting.
* Pre-conditions: start l3-agent with dvr_snat mode in all computer and network
nodes and set enable_metadata_proxy to true in l3-agent.ini.
* Step-by-step reproduction steps:
1.create a network and a subnet under this network;
2.create a router;
3.add the subnet to the router
4.create an instance with cirros (or other images) on this subnet
5.open the console for this instance and run command 'curl
http://169.254.169.254' in bash, waiting for result.
* Expected output: this command should return the true metadata info
with the command 'curl http://169.254.169.254'
* Actual output: the command actually returns "curl: couldn't connect
to host"
* Version:
** OpenStack version (Specific stable branch, or git hash if from trunk):
Mitaka
** Linux distro, kernel. For a distro, it’s also worth knowing specific
versions of client and server: all hosts are centos7
** DevStack or other _deployment_ mechanism?
* Tags (Affected component): l3-agent dvr metadata-proxy
** Affects: neutron
Importance: Undecided
Status: New
