<br>
Just an update to this issue. <br>
I make it work by adding a DNAT iptables rule on the WNs,
redirecting connection destined to 169.254.169.254 to
<controller ip>:8773. <br>
I thought this is taken care of by openstack automatically, maybe
not? Or am I on the wrong track? <br>
<br>
Thanks,<br>

How can I check the value of $my_ip? <br>
<br>
I notice that in the arp table on the instance, the entry for ip
169.254.169.254 has a wrong mac address, which I don't see
existent on both the controller<br>
node and the worker node. After I change the entry for ip
169.254.169.254 to map to the real mac address of the controller
host(metadata host as well), <br>
the curl command works. But, I don't know why the initial wrong
mac address gets entered into the arp table in the first place?
<br>
<br>
Thanks,<br>

In my essex install on RHEL6, there is a problem with the
metadata service.<br>
The metadata service works for instances running on the
controller node, where<br>
the nova-api(metadata service) is running. But for the
other worker nodes,<br>
the metadata service is intermittent, ie. the instances
sometimes can get its metadata,<br>
sometime it fails with errors like:<br>
<br>
$> curl -v <a moz-do-not-send="true"
href="http://169.254.169.254:8775/" target="_blank">http://169.254.169.254:8775/</a><br>
* About to connect() to 169.254.169.254 port 8775 (#0)<br>
* Trying 169.254.169.254... Connection timed out<br>
* couldn't connect to host<br>
* Closing connection #0<br>
curl: (7) couldn't connect to host<br>
<br>
Any idea where should I start investigating this?<br>
<br>
Thanks,<br>
Xin<br>
