I am now using the FlatManager network mode, when I allocate a floating ip to a instance with nova api command:
nova floating-ip-create
I get the error log in the server side:

It is ok if I change the network mode to FlatDHCPManager. I read the nova source code and found that FloatingIP
is the only class that have the "allocate_floating_ip" method and FlatDHCPManager is a subclass of this class， but class FloatManager is not a subclass of this class:
Code piece from network/manager.py:
class FlatDHCPManager(RPCAllocateFixedIP, FloatingIP, NetworkManager):
class FlatManager(NetworkManager):
