Public bug reported:

Service Subnets[1] were added in Newton.

The TL;DR is that a subnet can be created/updated with one or more
service_types corresponding to a port device owner. If a subnet has one
or more service_types, then only ports with a matching device owner can
be created on the subnet.

If a service subnet is created with dhcp enabled, automatic dhcp port
creation fails, because the port device owner does not match the
subnet's service_types.

The port creation is re-attempted over and over, and the subnet remains
without dhcp.

Steps to recreate:

NOTE: THIS REQUIRES INSTALLING OPENSTACKCLIENT FROM MASTER

$ openstack network create test-net

$ openstack subnet create test-subnet --subnet-range 10.1.0.0/24 \
  --service-type compute:nova --network test-net

Then take a look in the q-svc logs.
