You are correct, single vCPU can only utilize single core at a time.

It is rumoured that next major vSphere release will support 16 vCPU VMs, but you need lots of cores on single pCPU to benefit much of that. If you run 16 vCPU VM on modern quad socket system with quad core CPUs your NUMA locality will be very poor and performance may not be what you expect.
