Yes, ack from me too.

I'm still going to deprecate these in the OCaml bindings, or maybe
just change them so you can only do physical pointer comparisons.  I
just can't see a real life use for them ...  You already know which
call failed and from that what domain it was operating on, so except
perhaps in the case of migration there is no new information here.
Also I've not seen any libvirt program yet which does more than just
print the error message and either abort or ignore it.

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
