Public bug reported: Nova returns with 5xx response instead of 4xx in case of user error.
In this case it is clearly user issue, the user can know the 10.0.0.3 ip address already allocated from the subnet and it cannot be allocated twice. nuva must return with 409/Conflict status code and state the problem to the user as neutron did to nova. $ nova boot --image cirros-0.3.5-x86_64-disk --flavor 42 --nic net- id=ef952752-b81c-478e-a114-04083c63827c test $ nova list +--------------------------------------+------+--------+------------+-------------+--------------------------------------------------------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+------+--------+------------+-------------+--------------------------------------------------------+ | 7a453305-2684-4684-8005-04a98aebfc7e | test | ACTIVE | - | Running | private=fd64:8b83:fea2:0:f816:3eff:fe5f:3da3, 10.0.0.3 | +--------------------------------------+------+--------+------------+-------------+--------------------------------------------------------+ $ nova interface-attach 7a453305-2684-4684-8005-04a98aebfc7e --net-id=ef952752-b81c-478e-a114-04083c63827c --fixed-ip 10.0.0.3 ERROR (ClientException): Unexpected API Error.

In this case it is clearly user issue, the user can know the 10.0.0.3 ip address already allocated from the subnet and it cannot be allocated twice. nuva must return with 409/Conflict status code and state the problem to the user as neutron did to nova. $ nova boot --image cirros-0.3.5-x86_64-disk --flavor 42 --nic net- id=ef952752-b81c-478e-a114-04083c63827c test $ nova list +--------------------------------------+------+--------+------------+-------------+--------------------------------------------------------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+------+--------+------------+-------------+--------------------------------------------------------+ | 7a453305-2684-4684-8005-04a98aebfc7e | test | ACTIVE | - | Running | private=fd64:8b83:fea2:0:f816:3eff:fe5f:3da3, 10.0.0.3 | +--------------------------------------+------+--------+------------+-------------+--------------------------------------------------------+ $ nova interface-attach 7a453305-2684-4684-8005-04a98aebfc7e --net-id=ef952752-b81c-478e-a114-04083c63827c --fixed-ip 10.0.0.3 ERROR (ClientException): Unexpected API Error.
