OpenNebula LVM数据存储使用场景问题

2024-6-2 • tag-icon

我尝试在由两台主机组成的测试环境中配置 OpenNebula：

星云（前机）带日光石
kvm-节点-1已配置 VG 的主机

星云机器包含以下内容：

kvm-节点-1机器包含以下内容：

我可以通过 Sunstone 将带有映像的虚拟机部署到虚拟机管理程序。此图表示启动成功。但由于错误，我无法终止虚拟机：

我应该如何使用 LVM 数据存储来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？

答案1

这个问题已经被我在OpenNebula论坛解决了。

简而言之：

我已经解决了我的问题，特别是通过删除 id 0 的默认系统数据存储。现在，虚拟机实例正在正确的 VG 中创建（vg-one-104 而不是 vg-one-0）。我不知道这是否是正确的行为（删除默认的系统数据存储），但现在它对我有用。因此，VM 实例也可以正确终止。我将这个主题设置为已解决。

所有主题位于这个链接。
