In other words, we will only invoke the RTDS scheduler at specific scheduling event (such as VCPU budget replenishment, VCPU wake up, VCPU deadline arrives). This will reduce the frequency of invoking the RTDS scheduler and thus reduce the scheduling overhead in hypervisor. Another improvement is supporting getting/setting each VCPU's parameters in xl tool. Chong Li (chong...@wustl.edu), cc.ed, is working on this right now. He will finish the first version of the patch soon and we will go though some internal code review before sending out the patch to the mailing list. As to the progress, Dagaen finished the first version of the patch and we are going through internal code review and refining the code. We will send out the patch to the mailing list once we are satisfied with the code. (The status about this item should be marked as none now.)
