Yes. This is correct.

AFAIK in Essex, the metadata service was pointed out through iptables.
So there was a rule that DNAT the metadata service to the CC machine.

I had this metadata problem too, but I couldn't find out a proper solution.
My guess is that this problem is related to the Gateway/Router in
Folsom+Quantum installation. Or maybe in the metadata_host in the
nova.conf file.

I hope someone could clarify this things for us.


regards.
