Given your arguments, I'm okay with the idea, but like Laine pointed
out, it might be wise to get feedback from the opennebula guys first
(commit b811851 shows that Abel Míguez Rodríguez was the original
contributor in May 2009, now in cc).

As for the patch itself, I think you got most of the places that
referred to ONE or OpenNebula. You missed docs/api_extension, but that
was just demonstrating how to stub a new function into existing drivers
and represents a historically accurate snapshot, so that's okay. You
also left VIR_FROM_ONE in include/libvirt/virterror.h; although you
can't really delete that (for back-compat API reasons) you might want to
add a comment that it is deprecated. You missed po/POTFILES.in ('make
syntax-check' won't catch uncommitted file additions or deletions,
unfortunately). You also missed a mention in tools/virsh.pod.
