Subject: [Ksummit-discuss] [TECH TOPIC] Torwards a more scalable KVM hypervisor
Date: Wed, 12 Sep 2018 00:39:26 +0000 [thread overview]
Message-ID: <SG2PR02MB1312314C35B7B82C5EF34A50801B0@SG2PR02MB1312.apcprd02.prod.outlook.com> (raw)
The kvm hypervisor is at the core of cloud computing, Virtual Machine based approaches to workload consolidation, as seen in IaaS cloud as well as data center platforms, have long had to contend with performance degradation caused by synchronization primitives inside the guest environments. These primitives can be affected by virtual CPU preemptions by the host scheduler that can introduce delays that are orders of magnitude longer than those primitives 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
