创建计算节点时，“_allocate_network_async”在 amqpdriver.py 中引发错误 'Permession dennied'
When creating compute node, '_allocate_network_async' threw Error 'Permession dennied' in amqpdriver.py
我在写 nova driver。 driver 只是包装了我们服务的一些 REST api。
创建计算节点时，出现"Permission denied"错误
amqpdriver.py:341.
我已经调试了一个下午，但没有成功。
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 driver 无关。
有人可以帮忙吗？
