For example, one disk of one guest is hot plugout, its other disks
should not be affected if those disks also enable I/O throttling. But
if one whole VM need to be stored, all throttled requests for all

If one guest has multiple disks with enabling I/O throttling function
separately, when draining activities are done, some requests maybe are in the
throttled queue; So we need to restart them at first.
Moreover, when only one disk need to be drained such as hotplug out, if an
