Thank you for applying it. I will try "syntax-check" next time.

Yes, the hypervisor access should be used for root user.
But if a domain is inactive, we cannot see/set the scheduler parameters 
with visrh command even though xm command can do it since we cannot 
access to the hypervisor.
And also, we cannot allow to see the scheduler parameters for user who 
connect with read-only for the same reason.

For such case, I thought we needed the patch to access with Xend driver.

    thanks a lot,
    
Saori.
