Right. '-nographic' is just sending the host terminal input
to the guest serial port. Backspace works for me, so the
problem is likely either (a) the guest config or (b) the
host config (and my first guess would be (a) here).

Unfortunately keyboard handling has a lot of different layers of
software between your keypress and something actually happening,
and with a VM setup there are now two copies of these layers, so
it's not easy to say where exactly the problem might be. There
used to be Linux HOWTO documents purely on the questions of
backspace and delete and how to configure things :-)
