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>
<b>Here is the error from the log of nova-api:</b><br>
