You just need access to precise timers to tell if you are virtualized. If you can measure how long a full TLB miss takes vs just a cache miss you should be able to tell how deeply is your page table nested.

An emulator can emulate timers however it likes...

Ok, but that means that you can't have accurate wall clock time inside your virtual machine. Also, it would make most games impossible as all physics is ultimately tied to a clock. And of course a connection to internet is impossible.
