Title:
Return 409 at neutron-client conflict
Status in OpenStack Compute (nova):
New
Bug description:
Description
===========
When attaching a stateless and stateful security group to a VM, nova returns
a 500 error but it's a user issue and a 409 conflict error should be returned.
Steps to reproduce
==================
1. create network
2. create VM "test-vm" attached to the network
3. may create a statefull security group, but default group should already do
4. openstack securit group create --stateless stateless-group
5. openstack server add security group test-vm stateless-group
Expected result
===============
Nova forwards the 409 error from Neutron with the error description from
Neutron.
Actual result
=============
Nova returns:
Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/
and attach the Nova API log if possible.
