Incorrect.
If setup in bridged mode, then the host/hypervisor and it's network 
layer is as invisible to the outside as an ordinary L2 network switch 
would be. Only if the host/hypervisor was setup in routed mode would 
you see it as a hop in traceroute - but that would not be 
distinguishable from any other router.

It might help if instead of describing ways you can think of doing 
it, you described what you actually want to achieve. And why !
