Title:
  dhcp_release not called causing new VMs to fail DHCP

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in neutron havana series:
  Fix Committed

Bug description:
  I've found some situations where dhcp_release is not called when a
  port is deleted.  When this happens, dnsmasq refused to give out the
  IP to a new port when the IP address gets recycled.  The result is
  that the VM with the new port cannot get its IP address on boot.

  There are a few conceivable scenarios that lead to this.  I will
  attempt to describe some in the comments.
