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
