OpenNebula LVM 数据存储使用场景问题

  • 772

我已经尝试在测试环境中配置 OpenNebula，由两台主机组成：

  • 带有太阳石的星云（前置机）
  • 已配置 VG的 kvm-node-1主机

星云机包含以下内容：

root@nebula:/var/lib/one/datastores# onedatastore list

kvm-node-1机器包含以下内容：

我可以通过 Sunstone 将带有映像的 VM 部署到虚拟机管理程序。此映像已成功启动。但由于错误，我无法终止 VM：

我应该如何使用 LVM 数据存储组织前端机器和管理程序机器之间的交换来解决这个问题？

kvm lvm

    我已经在 OpenNebula 论坛中解决了这个问题。

    简而言之：

    我已经解决了我的问题，特别是通过删除 id 为 0 的默认系统数据存储。现在，VM 实例正在正确的 VG（vg-one-104 而不是 vg-one-0）中创建。我不知道这是否是正确的行为（删除默认系统数据存储），但它现在对我有用。因此，VM 实例也正确终止。我将此主题设置为已解决。
