With Neutron Newton version
There are two networks named share_net and test1 in my env, each with one subnet. When I create port in share_net, but specify subnet_id of the test1's subnet, not the subnet of share_net. Create port failed, but log is "Failed to create port on network 8fd6c0d1-e499-4e29-9786-dadb377f9939, because fixed_ips included invalid subnet d213e64e-045e-4941-a4bd-ffc049ad792c."
Here we can see network 8fd6c0d1-e499-4e29-9786-dadb377f9939 is test1, subnet d213e64e-045e-4941-a4bd-ffc049ad792c is the subnet of test1. The log is confused, actually it should log network 311a12a8-6824-4348-b5b5-80068a0c3785 with invalid subnet d213e64e-045e-4941-a4bd-ffc049ad792c.

Neutron server returns request_ids: ['req-e32df57b-0756-4b88-b042-a0b67ccd7fe7']
after inspect code, I found the function code is:
def _get_subnet_for_fixed_ip(self, context, fixed, subnets):
# Subnets are all the subnets belonging to the same network.
if not subnets:
msg = _('IP allocation requires subnets for network')
raise exc.InvalidInput(error_message=msg)
if 'subnet_id' in fixed:
def get_matching_subnet():
for subnet in subnets:
if subnet['id'] == fixed['subnet_id']:
return subnet
subnet = get_matching_subnet()
if not subnet:
subnet = self._get_subnet(context, fixed['subnet_id'])
msg = (_("Failed to create port on network %(network_id)s"
", because fixed_ips included invalid subnet "
"%(subnet_id)s") %
{'network_id': subnet['network_id'],
'subnet_id': fixed['subnet_id']})
raise exc.InvalidInput(error_message=msg)
this function, it use “'network_id': subnet['network_id'] ”, actually it should use the network passed from api.
