CVM使用动态内存 - 为什么？

我们的CVM配置了32GB的动态内存。开始，最小值和最大设置为32GB。我很想知道为什么在这些VM上启用动态内存？

由于CVM的OS并未完全集成Hyper-V，因此我们看不到该管理程序的内存需求（这是我在所有值设置相同的VM上启用动态内存中看到的唯一好处）。

作为明确的缺点，由于我们在这些VM上使用了动态内存，因此我们将失去VNUMA功能集（不是32GB VM是可能从中受益）。

谢谢！

\nSorry for the delayed response here. As you mentioned we do not benefit from vNUMA and the current configuration was a workaround for a Hyper-V bug. We're looking at changing this back to static in future releases assuming the original issue has been resolved.

\nSince the CVM's OS isn't fully Hyper-V integrated, we don't see memory demand from the hypervisor (this is the only benefit I see from leaving dynamic memory enabled on a VM with all values set the same).
\n
\nAs an explicit downside, since we're using Dynamic Memory on these VMs, we lose the vNUMA featureset (not that a 32GB VM is likely<\/i> <\/b>to benefit from it).

对不起，这里的回复延迟。正如您提到的，我们不会从VNUMA中受益，当前的配置是Hyper-V错误的解决方法。假设已经解决了原始问题，我们正在考虑将其更改为静态版本。
