Hi Steven,
Your sketch for the xm configuration magic was quite helpful. Perhaps
you can lend me a hand with resume as well.
xm restore fails (xend.log appended) because the xenfb backend can't
be connected. Obviously, I need to start the backend somewhere on
restore, just like I start it on xm create (patch appended). Where?
How?
