It looks like you are proposing an English language version of this
talk from LinuxCon China:
https://lc32018.sched.com/event/ER9W/torwards-a-more-scalable-kvm-hypervisor-wanpeng-li-tencent-cloud
Is that correct? I wasn't able to find slides from the LinuxCon China
presentations. Are they available?
Thanks,
