Yes, you have two choices:
1) use cgroups to throttle I/O at the level of the host disk (i.e.
multiple virtual disks stored on the same disk share the limit). If

Hello,
By the way, is there plans to enhance qemu I/O throttling to able to
swallow peaks or to apply various disciplines? Current one-second flat
discipline seemingly is not enough for uneven workloads especially
when there is no alternative like cgroups for nbd usage.
Thanks!

This is a followup to RFC posted by Shirley Ma on 22 March 2012 :
NUMA aware scheduling per vhost thread patch [1]. This patch is against
3.12-rc4.
This is a step-down from the previous version in the sense that
this patch utilizes the workqueue mechanism instead of creating per-cpu
