[openstack-dev] dhcp port creation

I have observed this behavior as well. Without digging in to recall
the details, I believe that when the DHCP agent restarts, it makes a
call that schedules any unscheduled networks to it.  Upon scheduling
the network to the agent, the port is created by the agent.

Without restarting the DHCP agent, the normal behavior is to wait
until a VM port is spawned on the network to schedule the network to
an agent.

I think the answer to your question is that this is expected but may
be surprising to some.
