Nova 计算状态“关闭”

  • 772

我正在 OpenStack 集群中进行实时迁移测试。（三鹰）。我在 2 个计算主机上部署了 3 个虚拟机。当我启动集群时，nova-compute 状态为 UP。但是一段时间后，尽管状态为已启用，但状态已关闭，因此我的虚拟机中断了。

    关于 rabbitmq 问题或一般网络问题，我将同意“eblock”。如果 nova-compute 已启用并正在运行，但无法与控制器可靠通信，它将显示为“关闭”。有时重新启动 nova-compute 服务可以解决问题，并且不会影响任何正在运行的虚拟机。

    检查主机上的 nova-compute.log 并查找超时、丢失连接等迹象。另外，查看控制器上的 rabbitmq 日志。希望有所帮助。
