我已成功使用 Landscape Autopilot 在 6 台机器上部署 Openstack。我可以创建实例（无卷）和其他东西。
在我尝试通过 Horizon 或 Openstack 客户端 CLI 将卷附加到实例之前，它似乎运行良好。它总是失败。在 Horizon 中，没有错误消息。
当我尝试在启用“创建新卷”的情况下创建实例时（在 Horizon 中），也会发生类似的问题。在这种情况下，出现一条错误消息：
"Error: Failed to perform requested operation on instance "xxxxxx" the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available]"
有关更多信息，我使用 Ubuntu 16.04 LTS、MAAS 版本 2.1.3、Juju 版本 2.1.2 和 conjure-up 作为工具来部署 Openstack。
请帮助我。我部署 Openstack 已经一个月了，但这个问题还没有解决。
更新
这是 nova-compute.log（当我尝试将卷附加到实例时出现的那个）

答案1
当您启动实例时 -- 在“源”选项卡中 --- 选择“否”以创建新卷。您应该能够启动一个实例。这是启动实例的解决方法。
当我尝试通过 CLI 或 Horizon Dashboard 连接卷时遇到了同样的问题。
$ openstack 服务器添加卷 24cf0c37-da44-4765-810c-569a64rfq5b0 ae6c0a48-09e4-411e-958a-60f3mrau1120 --设备 /dev/vdb $ $
没有错误。
当我检查服务器时，没有附加任何卷。
谢谢，MRAU
