can add some hack codes like this:<br>

'disk_write_bytes_sec', 'disk_write_iops_sec',<br>

# Note(yaguang): Currently, the only tuning available is Block I/O<br>
# throttling for qemu.<br>
if self.source_type in ['file', 'block']:<br>
for key, value in extra_specs.iteritems():<br>
scope = key.split(':')<br>
if len(scope) > 1 and scope[0] == 'quota':<br>
if scope[1] in tune_items:<br>
setattr(info, scope[1], value)<br>
</div>+ if not getattr(info, 'disk_total_bytes_sec'):<br>
