It turned out that extra white space in the neutron.conf file was
causing the issue. After i removed the whitespace, it works fine..

Title:
  on VM launch Unexpected vif_type=binding_failed

Status in OpenStack Neutron (virtual network service):
  Invalid

Bug description:
  I am running Icehouse on Ubuntu 14.04. Whenever I try to launch a VM it immediately goes into error state. 
  This is simillar to Bug #1303998, which was recently triaged and found to be a config error.  I have rechecked all my configurations and they look fine. 

  I have 3 node cloud, 
  Controller node - runs controller and network nodes. Compute1 and compute2 are the compute nodes.
  I have configured the gre tunnels as per the http://docs.openstack.org/trunk/install-guide/install/apt/content/section_neutron-networking.html 

  
  The nova-compute log file shows the following:
