openstack kilo can't launch a instance nova-conductor's and nova-compute's log have error

[elrondwang]

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:

Your description doesn't explain why this was opened as a private security vulnerability report. If this was meant to be a normal bug report, please switch it from "private security" to just "public" so that the nova developers will be able to see it. Thanks!

@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.
