14 常见问题
14.1 获取swift_temp_url报错
MissingAuthPlugin: An auth plugin is required to determine endpoint URL。因为我们选择了Direct的部署方式，裸机服务器的IPA会从Swift Object Storage将User Image拉到本地，在裸机端完成镜像注入，但是我们环境中没有部署Swift，所以需要改为ISCSI的部署方式。
PXE-E51: No DHCP or proxyDHCP offers were received。这是在为裸机MAC地址分配IP地址时发生的报错，主要原因是因为DHCP服务器与裸机网络不通，需要确保DHCP服务器与裸机之间可以通信。检查Neutron的配合文件，测试Provisioning网络的可用性。
