Well, that's something I haven't found in any Xen book - have to say, I
didn't read line after line, but my general impression was that most of
the available books covers pretty much the same topics - great for
beginner,  in case of better Xen book nice for more skilled xen user (to
find out how the stuff really works and what's possible) but for the
"PRO" users there's not that much...problem is, that Xen is evolving
fast and books are always 1-2 late (at the best) and that Xen
environment is different in every distribution (and they are evolving
even faster than Xen in many cases). :)
