Public bug reported:
When I run tempest run
neutron.tests.tempest.api.test_subnetpools.SubnetPoolsTest.test_create_subnet_from_pool_with_subnet_cidr
I see below warning in neutron-server
Apr 02 08:46:28 test.rdocloud neutron-server[12690]: WARNING
neutron.api.rpc.handlers.dhcp_rpc [None
req-4bfb3f1d-659f-49b8-8572-c74e7d955731 None None] Action create_port for
network 8e90dae6-018e-4979-bfad-2cc96e281ea8 could not complete successfully:
No more IP addresses available on network
8e90dae6-018e-4979-bfad-2cc96e281ea8.: IpAddressGenerationFailure: No more IP
addresses available on network 8e90dae6-018e-4979-bfad-2cc96e281ea8.
This test tries to create a subnet with cidr 10.11.12.0/31 i.e only one
address to allocate(which will be taken for gateway_ip). This subnet
creation will notify dhcp agent, which will try to create a dhcp port
but will fail as there are no address available. Still the subnet create
api will be successful as port creation is triggered later from dhcp
agent.
These tests may fail with vendor's drivers if their implementation try
to create dhcp port as part of subnet creation. There is no point in
creating a subnet with no IP address. Better to change the tempest tests
to provide CIDR with adequate addresses.
