Judging by one private reply I got, I don't want this to be misinterpreted. Libvirt DOESN'T expose the minimum subset of all hypervisors (because that would be very small and useless). It exposes general virtualization features, even if those features only apply to one or two hypervisors. For example: migration - only works with Xen & KVM, but could be applicable to other hypervisors in the future when we support them and they support migration scheduler tuning - only for Xen, but generally applicable adding/dropping interfaces from live guests - a general feature supported by many but not all of the backends Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones Read my OCaml programming blog: http://camltastic.blogspot.com/ Fedora now supports 60 OCaml packages (the OPEN alternative to F#) http://cocan.org/getting_started_with_ocaml_on_red_hat_and_fedora
