Hi,<br>
Just a few questions:-<br>
1. Can you please check /etc/quantum/metadata_agent.ini to see that
you have the correct quantum keystone credential configured?<br>
2. Can you please make sure that you are running the quantum
metadata proxy.<br>
3. In nova.conf can you please see that
"service_quantum_metadata_proxy = True" is set.<br>
Thanks<br>
Gary<br>

Hi there,<br>
<br>
I've installed Grizzly on 3 servers:<br>
compute (howard)<br>
controller (leonard)<br>
network (rajesh)).<br>
<br>
Namespaces are ON<br>
Overlapping IPs are ON<br>
<br>
When booting, my VMs can reach the metadata server (on the
controller node), but it responds a "500 Internal Server Error"<br>
<br>
