This feature will enable the user to cap disk I/O amount performed by a VM.It is important for some storage resources to be shared among multi-VMs. As you've known, if some of VMs are doing excessive disk I/O, they will hurt the performance of other VMs.Hi Zhiyong, Why not use kernel blkio controller for this and why reinvent the wheel and implement the feature again in qemu?
blkio controller only works for block devices. It doesn't work when using files.
