Hi,

I have found something maybe bug in nova-network

ie: using FLATDHCP my br100 is set 10.200.200.2,hostname=node1

when I start nova-network, br100 will be add an other ip, maybe 10.200.200.5

here in nova db, fixed_ips table , 'host' field of address="10.200.200.5" entry will be set to 'node1'.

then I kill the nova-network, and start it again, it will show error

  File "/usr/lib/python2.7/dist-packages/eventlet/hubs/hub.py", line 336, in fire_timers
    timer()
  File "/usr/lib/python2.7/dist-packages/eventlet/hubs/timer.py", line 56, in __call__
    cb(*args, **kw)
  File "/usr/lib/python2.7/dist-packages/eventlet/greenthread.py", line 192, in main
    result = function(*args, **kwargs)
  File "/data/nova/nova/service.py", line 81, in run_server
    server.start()
  File "/data/nova/nova/service.py", line 141, in start
    self.manager.init_host()
  File "/data/nova/nova/network/manager.py", line 1150, in init_host
    super(FlatDHCPManager, self).init_host()
  File "/data/nova/nova/network/manager.py", line 502, in init_host
    self._setup_network(ctxt, network)
  File "/data/nova/nova/network/manager.py", line 1164, in _setup_network
    self.driver.update_dhcp(context, dev, network_ref)
  File "/data/nova/nova/utils.py", line 730, in inner
    retval = f(*args, **kwargs)
  File "/data/nova/nova/network/linux_net.py", line 611, in update_dhcp
    f.write(get_dhcp_hosts(context, network_ref))
  File "/data/nova/nova/network/linux_net.py", line 549, in get_dhcp_hosts
    host = fixed_ref['instance']['host']
TypeError: 'NoneType' object is not subscriptable

Then I need update host=NULL in db to start nova-network successfully

I think it is a bug
