The stack trace indicates this is a Neutron issue, likely cause by enabling
Designate/DNS integration, but still within Neutron / before Designate is
called. I've added an affects Neutron.

Title:
Neutron loadbalancer VIP port fails to create

Bug description:
When trying to create a Loadbalancer (v1) VIP with the command:
neutron lb-vip-create --address 10.97.0.254 --name vip-97 \
--protocol-port 22 --protocol TCP --subnet-id subnet-97 hapool-97
Where subnet-97 is a subnet to tenant-97, which have 'dns_domain' set
to an existing domain. The domain works - creating an instance +
floating IP on that will register the set dns_name in the domain.
However, the lb-vip-create will fail with
Request Failed: internal server error while processing your request.
Neutron server returns request_ids:
['req-ee6a68f1-ed8a-4f22-9dea-646fb97ff795']
and the log will say:

I'm somewhat unsure if this a problem with Designate or Neutron (the
log DO say Neutron), but on the other hand, this worked just fine
before I added Designate to the mix.. Feel free to reassign to
Neutron.
This is Neutron v4.2.0 and Designate v2.1.0 on Debian GNU/Linux
Sid/Unstable - Mitaka.
