你好Nutanix社区。升级我的AHV版本时，我有问题。我附上错误屏幕截图。我如何解决这个问题而没有任何电源，重启或其他动作？因为它生产环境。谢谢

Hi there @Tural<\/user-mention>\u00a0<\/p>

Did you expand your cluster with nodes containing \u201colder\u201d CPU than the original ones? For Example if your cluster were using G6 Nodes, Did you add some G5 nodes? or different Gen Xeon Processors?<\/p>

If the answer is\u00a0yes,\u00a0you need to power cycle (not reboot) every single VM running in the cluster to \u201cadopt\u201d to\u00a0lower CPU features,\u00a0if you don\u2019t do this that UVM\u2019s will not be able to migrate from a G6 node to a G5 or from \u201cnewer\u201d Xeon node to \u201colder\u201d. This is called EVC in VMWare environments.<\/p>

Here\u2019s a topic with a similar issue\u00a0https:\/\/next.nutanix.com\/how-it-works-22\/living-migration-between-old-and-new-processors-39360<\/a><\/p>

I\u2019m afraid that the KB that @Primzy<\/user-mention>\u00a0suggested you it\u2019s the only way to go. Anyway, you can still open a case for clarification.<\/p>

Hope this helps\u00a0<\/p>

你好呀 @tural.

您是否与包含的节点扩展了群集，其中包含“较旧”CPU的节点而不是原始的节点？例如，如果您的群集使用G6节点，您是否添加了一些G5节点？或者不同的Xeon处理器？

If the answer is yes, you need to power cycle (not reboot) every single VM running in the cluster to “adopt” to lower CPU features, if you don’t do this that UVM’s will not be able to migrate from a G6 node to a G5 or from “newer” Xeon node to “older”. This is called EVC in VMWare environments.

这是一个具有类似问题的主题https://next.nutanix.com/how-it-works-22/living-migration-between-old-and-new-processors-39360.

我怕这是kb @primzy.建议你这是唯一的方法。无论如何，您仍然可以打开澄清的案例。

希望这可以帮助
