2014-04-11 11:59:29 -0500 asked a question VM gets no IP address assigned, cannot ping

have IP address assigned to the VM, but I am not able to ping the VM form the DHCP Agent and Router namespace for that particular subnet. Moreover looking at the VM logs no IP address is getting assigned to it.

I am attaching the logs for VM generation.
