These pr= imitives can be affected by virtual CPU preemptions by the host scheduler t= hat can introduce delays that are orders of magnitude longer than those pri= mitives were designed for. In this presentation, Wanpeng Li will introduce = current progress to mitigate TLB Shootdown Preemption. In addition, Wanpeng= Li will also introduce Exitless IPIs to scale large VMs. Regards, Wanpeng Li
