This is because we store the IP address management data associated with a network is stored in the Nova database. As Yong mentioned, in Folsom we are storing IP address management data in Quantum itself, in which case network creation can happen directly via the Quantum API and Nova VMs will still be able to get IPs. </div>

<font style="font-size:10pt" color="#366092" face="Tahoma" size="2">Hi Dan and Others,<br><br>I am trying to understand the actions taken by Ryu when the new instance sends DHCP discover message to dnsmasq. When I launch new instannce it keeps on sending discover messages and controller keeps on dropping these messages. But looking at the traffic I couldn't exactly map which MAC address belonged to which entity. Can someone help me with my understanding of the MAC addresses. Using ifconfig , "ovs-ofctl show br-int" and "ovs-ofctl snoop br-int" (output shown after MAC addresses), I know exactly about some MAC addresses and can't figure out some of them:<br>
