Hi Dominik, Hmm.. "blkio.weight" is used to control the Minimal Maximal Bandwidth. If you'd like to control Max bandwidth to let your guests become I/O hungery. "blkio.throttle.*" should helps. But these tunables aren't supported by blkiotune for the time being. I'm considering to implement them in the future.
