s/emualtor/emulator/

ACK with that fixed, and seems safe enough for 1.0.3 if you see this in
time.  I had to go researching why you only printed errors for < -1; but
I confirm that in util/virxml.c, the function is documented as returning
-1 for not present, -2 for present but parse error; and as these fields
are optional, not present does not mean an error.
