我正在尝试在 QEMU/KVM 上建立一个小型云来试用 MAAS/Autopilot/JUJU。
我有4台虚拟机：
1）Ubuntu 16.04.1 x64：MAAS 控制器 2.0.0+bzr5189-0ubuntu1
2）Ubuntu 16.04.1 x64：节点 1（已部署）
3）Ubuntu 16.04.1 x64：节点 2（已部署）
4）Ubuntu 14.04.5 x64：节点 3（就绪）==> 自动驾驶仪安装目标
因此，我使 MAAS 中的第三个节点处于“就绪”状态，并尝试从 MAAS 控制器在其上安装 Autopilot，引导程序工作正常，并在可用节点 3 上自动部署了 Ubuntu Trusty，我有 SSH 访问权限。
但我在此过程中收到此错误：

好像我遗漏了一些用户/密码？除了 MAAS 主机和 MAAS 密钥之外，我没有收到任何其他提示。
答案1
我从头开始，一切都在 Ubuntu Server 14.04.5 LTS amd64（Trusty）上运行，并且 Autopilot 设置运行正常。
MAAS 控制器 => 版本 1.9.4+bzr4592
自动驾驶/景观 ==> 版本 16.06
