That represents the type of virtualization technology used by the processor and doesn't mean that your machine is run in a virtualized environment. Both the turbo boost and VT technology stacks are covered on the IBM page linked off of the page linked:

Now: as far as being able to tell if your OS is running inside of a VM, it can certainly be done through direct or inferred hardware fingerprinting; what you would not be able to detect using any method I'm aware of, is the number of running domains on an Oracle/SUN piece of hardware in an attempt to see if that physical box is shared out (outside of the XSCF interface).
Best bet .... ask your hosting provider and check your SLA.
