A change like this is incomplete without adding documentation to the
virsh man page (tools/virsh.pod) and in the help strings that document
the individual arguments in the source file.
Sorry about that, this is my first patch and so I am still figuring things out. I will add the details in virsh.pod. Can you elaborate a bit on the help strings in this context?

iops is a count rather than a byte size so i don't think the default
scaling function is a good fit since:
kiB -> 1024
KB -> 1000
k -> 1024
True, I hadn't thought of that. Should we use a scaling function at all here, since the usual values of iops[1] dont really need to be given in a short format like 1K or 1M?
