I'm stumped.
There is also a metadata proxy that runs in the qrouter namespace, you
can verify it's running and getting requests by looking at both iptables
and netstat output.
$ sudo ip netns exec qrouter-$ID iptables-save -c | grep 169
[16:960] -A neutron-l3-agent-PREROUTING -d 169.254.169.254/32 -i qr-+ -p
tcp -m tcp --dport 80 -j REDIRECT --to-ports 9697
[96:7968] -A neutron-l3-agent-PREROUTING -d 169.254.169.254/32 -i qr-+
-p tcp -m tcp --dport 80 -j MARK --set-xmark 0x1/0xffff
The numbers inside [] represent packets:bytes, so non-zero is good.
$ sudo ip netns exec qrouter-$ID netstat -anep | grep 9697
tcp 0 0 0.0.0.0:9697 0.0.0.0:*
LISTEN 0 294339 4867/haproxy
If you have a running instance you can log into, running curl to the
metadata IP would be helpful to try and diagnose since it would go
through this entire path.

Hi Torin,
If I run `ip netns exec qrouter netstat -lnp` or `ip netns exec
qdhcp netstat -lnp` on the controller, should I see anything
listening on the metadata port (8775)? When I run these commands I
don't see that listening, but I have no example of a working system
to check against. Can anybody verify this?
Either on qrouter/qdhcp namespaces, you won't see port 8775, instead
check whether meta-data service is running on the neutron controller
node(s) and listening on port 8775? Aslo, you can verify metadata and
neturon services using following commands
service neutron-metadata-agent status
neutron agent-list
netstat -ntplua | grep :8775
Thanks & Regards
Arun
