Title:
  nova: dhcp_release command not found on RHEL6

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  nova-network log has error on RHEL6.x where it tries to execute
  dhcp_release command and fails. Do we have any setting which has to be
  disabled which should have been done during installation? I think this
  works on Ubuntu so is there any replacement for this command on RHEL6?
