Why use Parrot (or another VM) if I have a translator?

Question

Why should I use a VM, such as Parrot, for a dynamic language that I use (Python, Perl, ...) if I already have an interpreter? What can I get due to the presence of another virtual machine between my code and my machine and using a separate interpreter?

(I'm new to VM, so maybe the answer is obvious)

EDIT

What is the advantage of Parrot VM for end users?
