Hi Ritesh, Can I precisely know is this what you meant in the below email? Kill dnsmasq process and start it again. Then restart the nova-network.

If it is there you can still kill the process and restart the nova-network , i think dhcp will start giving lease.

The controller and the compute nodes were restarted and I could see that only few VMs have network connectivity and for the others the connections are lost. For example, I have posted the log of a VM below cloud-init start-local running: Wed, 05 Mar 2014 20:23:18 +0000. up 4.30 seconds no instance data found in start-local cloud-init-nonet waiting 120 seconds for a network device. cloud-init-nonet gave up waiting for a network device. ci-info: lo : 1 127.0.0.1 255.0.0.0 . ci-info: eth1 : 0 . . fa:16:3e:60:36:8d ci-info: eth0 : 1 . . fa:16:3e:59:c7:35 route_info failed Waiting for network configuration... Waiting up to 60 more seconds for network configuration... Booting system without full network configuration... Can I seek any help to resolve this problem?
