Openstack 错误：未能连接接口（HTTP 500）（请求ID:req XXXX）

我启动了一个只有一个接口的实例。当我尝试将一个附加接口附加到正在运行的实例时，我遇到了此错误。有什么想法吗

我正在使用

中子

网络。另外，附加接口和现有接口位于不同的网络上。我正在

ubuntu14

上使用

Icehouse

nova interface-attach --net-id XXXX 
--fixed-ip 192.168.1.246 Test_a5

ERROR: Failed to attach interface (HTTP 500) (Request-ID: req-XXX)

我从nova compute.log中得到了这个错误表单

ERROR nova.virt.libvirt.driver [req-XXXX XXXX] [instance: XXXX] 
attaching network adapter failed.

Hi，很难从日志中分辨出来。您能否提供更多信息，例如，这是第一个接口，还是您正在尝试附加一个附加接口？你在使用Nova还是中子网络？两个接口是来自同一个网络还是不同的网络？另外，在nova和中子上启用调试可能会有所帮助。@Dave请检查我的编辑。还已启用调试和详细说明。
