背景：我正在关注http://www.ubuntu.com/download/cloud/install-ubuntu-openstack我有一台 PM（16 核，48GB RAM），运行 7 台（最初为空）虚拟机，这些虚拟机是使用 virt-install 创建的。我使用 virt-install 创建了两个 NAT 网络：“私有”网络，所有 7 台虚拟机都连接到该网络，“公共”网络，只有 2 台虚拟机连接到该网络。PM 运行 MAAS 并仅在“私有”网络上提供 DHCP 和 DNS。（我选择名称“私有”和“公共”是因为我假设其中一个所需网络将用于执行 MAAS/openstack-y 操作，另一个将用于访问最终部署在最终将创建的（嵌套）虚拟机上的任何服务）。系统已登记并投入使用，因此，在 Ubuntu 程序的第 3 步结束时，我有 7 个节点，所有节点都标记为“就绪”。
问题：按照 Ubuntu 程序中的第 4 步，我运行openstack-install，提供 MAAS 密钥，将 MAAS 服务器指定为“私有”网络上的 PM 的 IP，大约 15 分钟后失败。
其他信息：openstack-install 的 TUI 的状态行显示“正在下载最新的 Landscape Autopilot 包...”；~root/.cloud-install/commands.log 的底部显示：

我注意到 MAAS 在发生此错误之前的相当长一段时间内将一个节点标记为“已部署”，并且该节点已打开电源；其他节点保持“就绪”状态并已关闭电源。
救命！：我在谷歌上搜索了很多次，找到了很多关于 juju 和其他东西的参考资料，我希望不必这么快就熟悉它们，但没有找到适合这个特定错误的好东西。有什么想法吗？谢谢！
答案1
确保您已在 MAAS UI 中设置了电源管理，以便 MAAS 知道如何打开/关闭虚拟机。有关更多信息，请参阅此处：如何配置 MAAS 以便能够启动虚拟机
我看到的另一个问题是，您似乎以 root 身份运行安装程序。根据我们的文档，您需要以普通非 root 用户身份运行安装程序。有关运行安装程序的更多信息，请参见此处：http://ubuntu-cloud-installer.readthedocs.org/en/latest/multi-installer.guide.html
如果您已完成这两项操作，请将完整的commands.log粘贴到粘贴箱中。
