Hello, I'm trying to install OpenStack on a single node from source. I can create instances and local networks so far:

openstack server create --flavor m1.nano --image cirros --security-group default instance42
openstack --os-region-name=RegionOne network create net1
openstack subnet create --network net1 --allocation-pool start=,end= --dns-nameserver --gateway --subnet-range net1
openstack port create --network net1 port1

However, if I try set the host for a port, the command -

openstack port set --host controller port1

crashes with the following error message (/var/log/neutron/neutron-server.log):

 ERROR neutron.plugins.ml2.managers [req-50c89b31-d5fb-46a1-8e09-46c054a69d39 77451ce05dd64297bacee951bc285360 2cdfc024b9494abeba71c407efc3ac6a - default default] Failed to bind port 6208d0ae-f8bb-4dde-bd42-c4eeba2d6ba0 on host controller for vnic_type normal using segments [{'id': '6380e4c0-399d-4864-a015-b4b4a9577ef7', 'segmentation_id': None, 'network_id': '6fd74b5f-2e6f-452d-8832-411229b37fa3', 'physical_network': None, 'network_type': 'local'}]

Why does this error occur? Is there anything I have to consider running OpenStack on a single node?

A thought (I don't have a running cloud for checking): I could imagine that not too much work goes into testing and debugging the local ML2 type driver; can you try vxlan or gre as tenant network driver?
