Yes.  I'm not worried.  The switch to gtk is a pretty big one anyway
with a bunch of user interface changes.  If we want avoid surprises for
the user at any cost we must not make gtk the default ui.

Also:  Once I'm done with the console cleanup it will be easy to make
'vc' actually work with gtk.

No.

'vc' is a DisplaySurface filled by the qemu terminal emulation.  It's
generic and works with any UI.

'vte' is a chardev data stream linked up to the gtk vte widget.
Obviously works with gtk only.

It just doesn't fit into the QemuConsoles at all, and with multiple UI's
active (such as gtk+vnc at the same time) it doesn't make sense any more.
