我们对Nutanix很陌生。我们从ESXi迁移到AHV。我们目前在ESXi上有某种程度的CPU超额订阅。我们预计在一些集群上需要超额订阅CPU，我正在寻找安全做到这一点的方法。我查阅了最佳实践指南，但那里几乎没有。任何帮助将不胜感激。

There is no difference for the AHV hypervisor whether it\u2019s vCPUs or cores per vCPU in the VM config.<\/p>

We always recommend to use vCPUs first, so if you need a VM with 4 CPUs in total - just use 4 vCPUs and 1 core per vCPU. The only purpose of those settings is that some older guest operating systems have limitations in the amount of cores and\/or sockets, so for legacy OSs it might be useful. Also, some software is getting licensed by the amount of sockets, then it might be useful to use multiple cores per vCPU to get less sockets. For performance there is no difference.<\/p>
