[求助/Help]关于热迁移的几个问题
关于迁移的问题:
环境: cloudpods 3.10.1
当前6个计算节点8C32G , 1个管理节点, 存储为 各节点的 localstorage
计算节点的cpu微码都一致, 且与管理节点不一致
将开机状态下虚拟机(8C8G) 从 管理节点 迁移到 计算节点 , 显示:
关机状态下在
管理节点 的虚拟机, 迁移到 计算节点 , 显示:
storage UUID not accessable
疑问:
- 是否只有 cpu microcode 完全一致的宿主机才能相互之间实现
热迁移 - 热迁移对于目标宿主机内存有何要求? 比如虚拟机为 8C8G, 热迁移时, 目标宿主机最少需要多少可用内存
- storage UUID not accessable` 这是什么意思? 目标宿主机是可以正常创建虚拟机的.
@saltfishh
- 目前的逻辑是用户控制是否进行 CPU 检查，如果跳过 CPU检查则可以在不同的 CPU直接进行迁移。实际上只有两边 CPU没有不兼容的 feature就能迁移（需要用户自己判断）
- 调度上要求至少 8C8G
- 是否改过调度代码，3.10.1没找到相关关键字

迁移时, 目标宿主机上没有任何虚拟机, 无论开机的还是关机的亦或是在回收站, 目标宿主机资源是足够容纳待迁移虚拟机的. 没有修改过源代码, 从github直接拉下的源码.
@saltfishh 你要迁移的虚机使用的本地存储吗
是的, 因为目前宿主机使用的都是本地存储, 要迁移宿主机, 是需要迁移存储过去的.
@saltfishh 使用浏览器debug模式看下 前端预调度传的参数是怎么样的，如果是本地存储的话可能是没有传迁移的参数
