[openstack-dev] [Neutron] Find the compute host on which a VM runs

I studied the portbindings extension (the quantum.db.portbindings_db and
quantum.extensions.portbindings modules). However it's unclear for me who
sets the portbindings.HOST_ID attribute. I ran some tests with OVS: called
quantum port-create command and the OVSQuantumPluginV2.create_port method
got called and it had 'binding:host_id': <object object at
<memory_address>>. If I print out the port object I have 'binding:host_id':
What other plugins are doing:
1. extend the quantum.db.portbindings_db.PortBindingMixin class
2. call the _process_portbindings_create_and_update method in create/update
What I cannot find is where the portbindings.HOST_ID attribute is being set.
