OK, I included the ‘q-meta’ service in the Devstack localrc, stopped and completely removed the packages (and associated files) installed by Devstack on the machine, and reinstalled Devstack. I do now see the ’q-meta’ service running in the screen log files. I also added a rule to  iptables’ nat table to DNAT 169.254.169.254:80 to <host_ip>:8775. However, when I start an Ubuntu UEC image, I’m still getting time outs on the URL for the metadata:

Am I still doing something wrong? I still have Quantum with overlapping ranges enabled, but I took Mark’s response below to mean that Devstack with ‘q-meta’ would handle this...

 

Thanks,

Will

Thanks for your response, Mark. Can you confirm that the 'q-meta'
service works in Devstack if Devstack was installed about a week or two
ago (we do have the 'RECLONE=yes' option set in localrc) or must we pull
latest from git again?

Best,
Will

Will-

The metadata service in Folsom will only work when overlapping IP ranges
are disabled (see:
http://docs.openstack.org/trunk/openstack-network/admin/content/ch_limit
ations.html).  For Grizzly, we have added metadata service for
overlapping networks.  This feature is currently available in devstack
when you enable the q-meta service.

iptables, with no luck... I still cannot reach the metadata server at
169.254.169.254:80. When I dump the iptables rules for the 'nat' table,
I see that my added rule is being hit, but it's still not working:
