It is not wasted. It is reserved. If it's not reserved then another
app on the host OS could take it. And then what will happen when the
guest OS *thinks* it has some memory available but in fact does not?
Then the host OS would begin swapping to disk. Then performance will
suck, processes will hang on the guest OS, also slowing the host OS to
a crawl with all that memory swapping going on.

If you are memory constrained, you shouldn't be doing virtualization
to begin with.

Just my $0.02, on a personal level, speaking just as a end user.
