I'm trying to launch an instance attached to an external network, but I get
an all host exhausted error message, and the neutron log file show the
following error :

*ERROR neutron.plugins.ml2.managers
[req-6979d5fd-8e6a-4802-a758-e4882b7ac5b6 397fa0267ae340e1b24a3a96ae302f32
05b9f31fca434f7a96b63a1d17e8b14c - default default] Failed to bind port
d57ac8f5-7904-495f-a4b9-9b23df681634 on host compute1.localdomain for
vnic_type normal using segments [{'id':
'475c70c2-6a35-4721-a726-cbf8c0b7e778', 'network_type': 'flat',
'physical_network': 'physnet2', 'segmentation_id': None, 'network_id':
'a1c2cc8f-6a04-48ce-9d87-a351da1d3f3e'}]*

But when I try to launch an instance using another external network, it
works just fine.
