MAAS KVM 无法调试节点：节点操作“调试”在 30 分钟后超时

更新

我发现，在提示登录之前，短暂的图像会闪现一条消息，说“无法应用阶段配置，未找到数据源“。经过一番研究，这可能与网络配置错误导致节点无法到达区域控制器有关。
节点位于配置为 10.17.17.0/24 的虚拟网络上，而 MAAS 服务器部署在 10.10.9.34

我应该如何更正我的网络配置？

原始问题

我有 MAAS 2.7，并且正在尝试调试使用 KVM 组成的节点，调试过程总是卡在“加载临时”状态，然后在 30 分钟后超时。

当我查看虚拟机时，它挂在ubuntu 登录屏幕PXE 启动后，我不知道该输入什么，我尝试了许多可能的凭证组合，但总是显示“登录不正确”。重新启动/重新调试后，它将再次通过 PXE 启动 -> 提示登录过程。

我可能搞错了我的网络配置：MAAS 服务器部署在物理机器上，然后我在同一台机器上使用 virt manager 创建了一个虚拟网络，并在虚拟网络上添加了 ssh 密钥。通过 MAAS 在此虚拟网络上启用了 DHCP。

答案1

虽然不是真正的修复，但我最终通过将 MAAS 降级到 2.6 来让它正常工作
