Add vCPU in VMware Fusion for Windows

As Windows Pro only supports 2 CPU sockets, after added 4 cores in VMware Fusion, the OS is still shown as 2 vCPU. To avoid this is, need to change cpuid.coresPerSocket to handle more than 2 cores.


In .vmx file change following parameter, numvcpus is the total number of cores, which can be changed in GUI. cpuid.coresPerSocket should be changed to half of numvcpus.

numvcpus = "4"
cpuid.coresPerSocket = "2"
