Eh, still why would you attach multiple subnets to an instance to do
this type of segregation? This use case doesn't make much sense to me.

  how to reproduce this error

  we need two subnets which belongs to one network 
  in my environment,
  network id is 5332f0f7-3156-4961-aa67-0b8507265fa5
  subnet1 id is e8a9be74-2f39-4d7e-9287-c5b85b573cca
  subnet2 id is dca45033-e506-42e4-bf05-aaccd0591c55 

  1. create ports  from subnet1 and subnet2

  quantum port-create --fixed-ip subnet_id=e8a9be74-2f39-4d7e-9287-c5b85b573cca  5332f0f7-3156-4961-aa67-0b8507265fa5
  port id is :  dca1f741-a1fc-444c-b764-7aa74ed29d1f

  quantum port-create --fixed-ip subnet_id=dca45033-e506-42e4-bf05-aaccd0591c55  5332f0f7-3156-4961-aa67-0b8507265fa5
  port id is : 72acaba1-6e84-468b-b3f7-52eb89972eb7

  2. boot with two port id

  nova boot --flavor 1 --nic port-id=dca1f741-a1fc-
  444c-b764-7aa74ed29d1f  --nic port-id=72acaba1-6e84-468b-
  b3f7-52eb89972eb7 --block_device_mapping vda=1cf2a0b0-8c7f-4de1-8dba-
  91bae1f1856c:::0 m1

  ERROR: The server has either erred or is incapable of performing the
  requested operation. (HTTP 500) (Request-ID: req-ea58ab37-aea6-40a4
  -b85f-2ab19285101e)

  it returns an error , and there is a NetworkDuplicated error  in
  /var/log/nova/nova-api.log
