Title:
Nova should not return a 500 on floating ip create with ipv6
Status in OpenStack Compute (nova):
Fix Released
Bug description:
Neutron does not support creating or using floating ips on an ipv6
network. When nova gets a create floating ip call and does the
passthrough call to neutron it will get a 400 response from neutron
saying there is not ipv4 subnet available. This goes unhandled by nova
and will cause a 500 response. Since this is an expected error, nova
should catch it and return a 400 to the user for the same reason.
For example logs with the unhandled exception see:
