@Moonlight -shadow (1403383953-h):

The error "Unexpected vif_type=binding_failed" could be caused by a
misconfiguration of Neutron. You could try [1] to resolve this. Also the
"nova.conf" configuration option "vif_plugging_is_fatal=False" [2] could
help you, depending on the purpose of your OpenStack installation. I
close this bug as "invalid". Please feel free to set this bug to "new"
again if you think that there is an issue which is not caused by a
misconfiguration.

  Bug Description
   
  environment:  openstack kilo centos7 tree node(controller nova neutron)

  when I launch a instance in dashborad,it masks a mistake.the prompt
  is: No valid host was found. There are not enough hosts available.].

  In controller node /var/log/nova/nova-conductor.log shows:
  File "/usr/lib/python2.7/site-packages/nova/scheduler/manager.py", line 86, in select_destinations
      filter_properties)

    File "/usr/lib/python2.7/site-packages/nova/scheduler/filter_scheduler.py", line 80, in select_destinations
      raise exception.NoValidHost(reason=reason)

  NoValidHost: No valid host was found. There are not enough hosts
  available.

  
  In compute node /var/log/nova/nova-compute.log shows:
