It looks like your network is multi_host=True. this is the only reason sonoma would have been assigned an ip. So you can either run nova-network on sonoma or set multi_host=0 on your network in the database. If you want to switch back to multi_host=0 you will likely have to clean out the db tables, so you might do best dropping all records from the networks and fixed_ips tables and recreating the network.<div><br></div><div>Vish</div><div><br><div><div>On Nov 20, 2012, at 4:52 PM, Ahmed Al-Mehdi <<a href="mailto:ahmed@coraid.com">ahmed@coraid.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; font-size: 14px; font-family: Calibri, sans-serif; "><div>Hi Vish,</div><div><br></div><div>Thank you very much for your help, I really appreciate it.</div><div><br></div><div>My setup has two nodes:</div><div><br></div><div>controller-node (hostname: bodega; nova-network running; no nova-compute running)</div><div><div><span class="Apple-tab-span" style="white-space:pre"> </span>eth0:<span class="Apple-tab-span" style="white-space:pre"> </span>10.176.20.158</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>eth1:<span class="Apple-tab-span" style="white-space:pre"> </span>No IP assigned (VM network)</div><div> </div></div><div>compute-node (hostname: sonoma; nova-compute running only). </div><div><div><span class="Apple-tab-span" style="white-space: pre; "> </span>eth0:<span class="Apple-tab-span" style="white-space: pre; "> </span>10.176.20.4</div><div><span class="Apple-tab-span" style="white-space: pre; "> </span>eth1:<span class="Apple-tab-span" style="white-space: pre; "> </span>No IP assigned (VM network)</div></div><div><br></div><div>My network configuration is in single-host mode.

do you have a machine with the hostname sonoma?
