It took me a while to work this out, so please mention that the VNC in
question is the backend corresponding to the stubdom's PVFB (into which it
writes the emulated VGA content) and that the port for that is written into
the PVFB frontend dir, i.e. on the stubdom path.

Or alternatively since semantically this is the guest's console (albiet
laundered through a stubdom) perhaps we should be writing these vnc-* keys
there instead/as well?

Either way these vnc-* keys need to be documented in docs/misc/xenstore
-paths.markdown, either directly or by a reference to pvfb.h (which would
then need to talk about them), so we know what they mean and where they
should live (which in turn may render at least half what I said above
moot).

Ian.
