With virtual symmetric multiprocessing (SMP), you can assign processors and cores per processor to a virtual machine on any host system that has at least two logical processors.
Workstation Player considers multiprocessor hosts that have two or more physical CPUs, single-processor hosts that have a multicore CPU, and single-processor hosts that have hyperthreading enabled, to have two logical processors.
On hyperthreaded uniprocessor hosts, performance of virtual machines that have virtual SMP might be below normal. Even on multiprocessor hosts, performance is affected if you overcommit by running multiple workloads that require more total CPU resources than are physically available.
You can power on and run multiple dual-processor virtual machines concurrently. The number of processors for a given virtual machine appears in the summary view of the virtual machine.
