No, sorry, nothing coming through. The question as phrased makes no
sense.

If you're asking where does a given address in the virtual address space
map to, it depends on whether the corresponding page of the process
address space is currently in RAM, or on backing store (disk or
whatever), or nowhere because it hasn't been allocated, but the question
"where is the address space" has no meaning.

Furthermore, the *machine* as such has no "virtual address space".
