Title:
  Host is always set to None in get_instance_nw_info(...)

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) grizzly series:
  Fix Released

Bug description:
  The the nova-network manager's method get_instance_nw_info(...) the
  host parameter get reset to None.

  This causes the host to be interpreted as the host where the nova-
  network process is running instead of the host that is passed in
  (which is usually the host where the instance lives). One side affect
  of this change is that the address of the DHCP server for an instance
  can get assigned to a random host depending on which nova-network
  process handles the get_instance_nw_info(...) call instead of the host
  where the instance exists.
