在创建计算节点时，＆＃39; _allocate_network_async＆＃39;扔错误＆＃39; Permession dennied＆＃39;在amqpdriver.py中

我正在写一个新手司机。驱动程序只包含了我们服务的一些REST API。

创建计算节点时，＆＃34;权限被拒绝＆＃34;错误被抛出 amqpdriver.py:341。

我整个下午都在调试，但没有运气。 我认为该错误可能是由有关消息传递服务器的某些权限设置引起的。而且我认为这与我们的司机没什么关系。 有人可以帮忙吗？

root错误发生在nova-network.log。

根据日志，某些文件操作会引发权限错误。

我专注于nova-compute，所以只需跳过操作而无需任何修复。 在nova.conf中，添加该选项，可以跳过大部分网络操作。

    fake_network=True

以下是nova-compute.log中的错误
