Swap can be started or stopped. Virtual memory cannot be started or stopped. Just because you stopped swap does not mean the kernel is not using virtual memory. The kernel always uses virtual memory (except if its MMUless) . Swap is used only when the kernel needs more memory than what's physically available.
