Maybe in a similar way to the credit scheduler's weight? You can already partition CPU-Time, RAM, Disk space, but not really Disk I/O...

I would = like to have a way to easily limit I/O for individual disks of virtual = machines (pv, hvm and hvm-studom).
Maybe in = a similar way to the credit scheduler's = weight?

You can already partition CPU-Time, = RAM, Disk space, but not really Disk = I/O...

William Pitcock seems to do some work on = a I/O QoS token-based approach, maybe this is a good = start?
