I'm not a virtualization person myself, so other people might offer you
more convenient sugestions but, with the due respect, I think you might
be better served by an introductory text on operating systems. The 3rd
edition of Andrew Tanenbaum's Modern Operating Systems, for instance,
has a short section specifically devoted to virtualization which is
clear enough to non-experienced readers and, I guess, answers most of
your questions.
