Hi Pranav, Thanks for the reply. Actually I'm using Redhat. Do you think we can execute the same command to recompile the Kernal?
Also, another behavior that really concerned me was that 'brctl show' does not list anything when we create the VM instances. Does this indicate that integration bridge is not functioning?

Can you do # dpkg-reconfigure openvswitch-datapath-dmks (assuming you are using ubuntu/debian) or something similar and check the output, esp. when its recompiling the kernel.

Thanks, YuLing From: C, Yuling Sent: Tuesday, December 17, 2013 6:47 PM To: [email protected]<mailto:[email protected]> Subject: vm instances could not get ip address from dhcp agent Hi All, I have an openstack installation environment of two nodes. One node contains Controller, Network, Nova, Glance, Keystone, Client, and Cinder. The other node is just a nova_compute node. Everything worked very well before. Suddenly we hit the issue that vm instances could not get ip addresses from dhcp agent. I looked into dhcp-agent.log, but didn't find much useful information. Just wondering if someone could shed some light on this issue. The behavior is that even the VMs created on node1, which contains Controller, Network, Nova, Glance, keystone, Client and Cinder could not get the IP from dhcp agent. When I use tcpdump -i br-ehter1, or tcpdump -i < physical Ethernet port id>, I was able to see the DHCP requests, but no reply from dhcp agent. Any idea?
