求助 nova 报错，怎么解决这个问题vif_type=binding_failed

这是我安装的compute节点运行，compute报错的错，

删除实例失败，先看看实例的状态是什么？
删除方法有三种：
1.通过命令删除
2.通过dashboard删除
3.在数据删除

这里其实是在创建实例，但是在计算节点创建实例失败了，我比较困惑的是在这里报的这个错 vif_type=binding_failed 我没发现哪里有配置vif_type的地方，

During wait destroy, instance disappeared.
是不是操作太快了，或则你在删除实例的时候删除失败了，一直处于删除状态，所以你创建实例，可能会受到干扰。

可能是ovs出问题了，也就是网络的问题，检查下通信、nettron、ovs等，如下代码，所以如果你是使用的ovs的话，那应该是ovs绑定失败了。推测原理：
虚拟机建立需要网络资源，但是绑定失败了

class OVSNeutronPluginV2(...):
   def __init__(self, configfile=None):
        self.base_binding_dict = {
            portbindings.VIF_TYPE: portbindings.VIF_TYPE_OVS,
            portbindings.CAPABILITIES: {
                portbindings.CAP_PORT_FILTER:
                'security-group' in self.supported_extension_aliases}}
复制代码

在代码中可以看到,其初始化为base_binding_dict['binding:vif_type']='ovs', 在之后的一些代码中会被update到port中.这个执行neutron port-show中可以看到对应的值,同时,在最后的libvirt的plug方法中也是起着判断因素的.
