Marcus Sorensen commented on CLOUDSTACK-1301:
---------------------------------------------
Several people may already be working on this, i have no idea if it made it
into an FS yet. the idea was to put it in the disk offering, and then the
storage would handle it, for example if its a San it may have iops
settings, or if its a local disk then the LibvirtStorageAdaptor might.

> VM I/O Throttling, to set the maximum disk I/O rate of VMs.
> Virtual machines are running on the same storage device (local storage or
> share strage). Because of the rate limitation of device (such as iops), if
> one VM has large disk operation, it may affect the disk performance of other
> VMs running on the same storage device.
> It is neccesary to set the maximum rate and limit the disk I/O of VMs.
