Hi,

Thanks for your reply. Has this solution been added to new credit scheduler? I am using Xen-3.4.2. And in this version, when the vcpu is de-scheduled, it seems the current vcpu is just inserted into runqueue and its credit is not deducted.

    if ( vcpu_runnable(current) )
        __runq_insert(cpu, scurr);
    else
        BUG_ON( is_idle_vcpu(current) || list_empty(runq) );

    snext = __runq_elem(runq->next);

Regards,
Cong

when the vcpu is de-scheduled, it's credits will be deducted.
