Ok, thanks for your answer.<br>So, that's mean the current trunk doesn't work with trio Nova+Quantum+Melange.<br>That's correct ?<br><br>Doude.<br><br><div class="gmail_quote">2012/2/29 Dan Wendlandt <span dir="ltr"><<a href="mailto:dan@nicira.com">dan@nicira.com</a>></span><br>

Hi Jason,<br>
<br>
Thank you very much for your answer.<br>
The problem about the wrong ip address is solved now! Perhaps this<br>
octect should be excluded automatically by nova at the network<br>
creation time?<br></blockquote><div><br></div></div><div>I agree that it seems reasonable to have the default exclude the .0 address. </div><div class="im"><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
Regarding the other problem about nova/melange, in fact, I creates all<br>
my networks with the nova-manage command:<br>
nova-manage network create --label=public<br>
--project_id=def761d251814aa8a10a1e268206f02d<br>
--fixed_range_v4=<a href="http://172.16.0.0/24" target="_blank">172.16.0.0/24</a> --priority=0 --gateway=172.16.0.1<br>
But it seems that the nova.fixed_ips table is not well filled.<br></blockquote><div><br></div></div><div>When using melange, the nova DB is not used to store IP address allocations. They are stored in Melange. We allow network create using nova-manage purely for backward compatibility. The underlying implementation is totally different, with Nova effectively acting as a client to proxy calls to Quantum + Melange. Hope that helps. </div>
