<body class='hmmessage'><div dir='ltr'>Hi,<div><br></div><div>This happened to me once. Firstly, check neutron logs for any errors in /var/log/neutron/. If you see errors post them here.</div><div><br></div><div>Secondly, Verify that neutron dhcp is running. Verify that you have configured OpenStack Data Network correctly, verify VLAN/GRE (whichever applicable) configurations from physical switch and then restart neutron services on control and compute nodes. Restart the VM and it should get the IP. This worked for me. </div><div><br></div><div>For further debugging you can use wireshark/tcpdump on the network interfaces/bridges on control and compute node during VM creation to see where the dhcp packet is getting dropped. </div><div><br></div><div>Regards</div><div>Moiz</div><div><br><div><hr id="stopSpelling">Date: Mon, 8 Sep 2014 17:15:28 +0530<br>From: srinivasreddy4390@gmail.com<br>To: openstack@lists.openstack.org<br>Subject: [Openstack] virtual machine not able to get ip address<br><br><div dir="ltr"><pre>hi,<br></pre><pre>I have configured 3 node setup with icehouse release. able to launch to instance . the instance is in active state with no errors ..but it is not reachable . <br></pre><pre>It is not able to get ip address ..
