DBDuplicateEntry error, create-port on IPv6 subnet

[isador999]

Hi,

We have four Openstack networks, each with two subnets (IPv4 / IPv6).
DHCPv6 is disabled on all IPv6 subnets.

Only on Net1 and Net2, we have a problem with : 'neutron port-create NETID1 --name MYPORT --fixed-ip SUBNET_IPv6_ID'
It returns : 'Internal Server error'

and /var/log/neutron/server.log returns :
 raise exception.DBDuplicateEntry(columns, integrity_error)
2014-09-15 08:10:57.359 50254 TRACE neutron.api.v2.resource DBDuplicateEntry: (IntegrityError) (1062, "Duplicate entry 'fd00:21:1::44-eccdf9d7-1278-4eb8-9747-7485fb2466db-868967b4-ce73' for key 'PRIMARY'") 'INSERT INTO ipallocations (port_id, ip_address, subnet_id, network_id) VALUES (%s, %s, %s, %s)' (('669c81b5-5f1c-4beb-88f7-61c0d5e8d772', '21.1.0.51', '8220d8ff-fe10-4137-bff7-ff2ea7270f13', '868967b4-ce73-4a88-8bfe-5c6c8f90a50d'), ('669c81b5-5f1c-4beb-88f7-61c0d5e8d772', 'fd00:21:1::44', 'eccdf9d7-1278-4eb8-9747-7485fb2466db', '868967b4-ce73-4a88-8bfe-5c6c8f90a50d'))

We can delete this IPv6 address from the database, but this IPv6 address is already used by an instance !

So, I don't know if Dnsmasq or neutron-dhcp-agent is the root cause, but we can see Openstack don't choose a different IPv6 address for each port...
Strangely, subnets on other networks (Net3, Net4) works perfectly.

[Ann Taraday (akamyshnikova)]

Create four networks with ipv4 and ipv6 subnets each, dhcp disabled on ipv6 subnets. For all ipv6 subnets ports are created without any 'Internal Server error'. Please, see http://paste.openstack.org/show/125761/. Please, provide more information may be step by step how such error appear and what plugins is used.
