参考官方文档的“从独立的Manager迁移到自托管引擎”。
测试用电脑：CPU i5-6500 8G内存
测试用系统： oVirt Node 4.3.10 / CentOS 7.8 (均存在这个问题)
已经测试过使用自托管引擎的备份文件执行同样的操作，并没有出现问题。
使用的“独立的Manager”为engine-setup设置完毕后的初始状态。（添加主机/储存的后的备份文件也有测试，问题依旧。）
执行命令如下：hosted-engine –deploy –restore-from-file=file.backup
报错信息如下：
[ INFO ] TASK [ovirt.hosted_engine_setup : Evaluate temporary bootstrap engine URL]
