On the Xen RoadMap for 3.0 a feature listed is:

"Enhanced QoS features. Xen already enables control over the CPU and
network usage of domains, but we plan to improve this support by adding
soft real-time scheduling capabilities to enable upper and lower bounds
to be set on a domain's resource usage. Providing better tools support
for disk scheduling and accounting is important too."

I keep track of the code changes and haven't seen anything specifically
for improved disk I/O accounting and QoS.  Has worked been done on this
(or perhaps something I missed) or is this a feature that we should not
expect to see?
