Okay, so then basically, if I understand the current state of the blkio
controller correctly (see my original message), this is useless at this
point.

I don't mean to offend you in any case, I just wondered how you used (or
intended to use) this, since I myself did not yet find a good way to
actually limit a guests I/O hunger.
