Public bug reported:

https://github.com/openstack/neutron/blob/master/neutron/objects/base.py#L563
In the above link, Neutron OVO create raises NeutronDbObjectDuplicateEntry on seeing duplicate entries when for example we try to do multiple API calls to create AutoAllocatedTopology for a project. This needs to be handled by retrying the transaction so will need the retry logic to catch this exception here https://github.com/openstack/neutron/blob/master/neutron/db/api.py#L59

Following Test Failure can be reproduced with this bug:

tempest.api.compute.admin.test_auto_allocate_network.AutoAllocateNetworkTest.test_server_multi_create_auto_allocate
[id-2e6cf129-9e28-4e8a-aaaa-045ea826b2a6]
