It means that you see the same view of memory that the
currently running guest process does -- its "virtual memory
space". It takes virtual addresses, which are passed through
the guest CPU's MMU, just as any memory access from the
guest process does. This is as opposed to the view of "physical
memory", which takes physical addresses and shows you
the underlying memory and devices that the guest OS
has access to.
