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

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
非淡泊無以明志，非寧靜無以致遠
