Title:
  nova network cannot allocate fixed IP

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  After deleting the previous created network, Openstack just clear the record in
  DB table networks, while marking fixed_ips table record *deleted* field to 1.

  Then I recreate the same network, Openstack network could not allocate the
  right IP from pool. The detailed log is as below:

  After deleting the record in fixed_ips table, whose *deleted* field marked as
  1, nova network could allocate fixed IP, and the system seems to be normal,
  the right log should be as below:
