Title:
  Nova Compute Error in nova-manage db sync

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  Hi All,

  Grizzly - I was successfully able to implement one controller node and
  a compute node, BUT when I tried to add another compute node with the
  controller I got below error. Per document I followed till stopping of
  the required services and then "nova-manage db sync". Not sure if it
  is because of nova database is already present in Controller and I had
  done the db sync for my first controller-compute configuration. If we
  need to drop the old nova database then its not the solution as every
  time it would be required when you will be adding the additional
  compute node.

  Please advise.

  Nova.conf is exactly the copy of working compute node and with my_ip,
  vnc details changed.

  Error on new compute node:
