I. Basic concepts
The number of processors refers to the number of virtual CPUs.
The number of cores per processor refers to the number of cores of the virtual CPU.
Total number of processor cores = number of processors? Number of cores per processor.
Here, the total number of processor cores of a virtual machine corresponds to the number of CPU threads (that is, the number of logical processors) of a real physical machine (or host).
So when setting up, we just need to make the total number of processor cores
