Hi,
This patch intends add a showing function of scheduler information.
If apply this patch to current revision 1.490
and type virsh dominfo 0
then shows following scheduler information.
Currently I assume credit scheduler only.
getting function is implemented but setting function is not yet.
I just waiting for comments.
Is this part of the patch correct?

My more general comment would be how Xen-specific is this? What
scheduler could be used by other drivers? (Obviously qemu just uses the
Linux scheduler. However I don't know what kvm uses - whether it also
schedules using the Linux scheduler, or some other method).
