The Must-Attend

Open Infrastructure Event

The open infrastructure landscape is changing, and so is the Summit. Now that users are integrating dozens of open source tools into a modern stack that reaches well beyond the scope of OpenStack, we’re re-organizing the event to focus on specific problem domains like container infrastructure, edge computing and CI/CD and we are focusing on the hard work of integrating all of these tools developed in disparate communities. This is the essential work of 2018 and beyond, to ensure that open infrastructure is truly a viable path for operators.

KVM and QEMU Internals: Understanding the IO Subsystem

This presentation will break down the plethora of options available for delivering storage to a virtual machine in KVM/QEMU. It will detail the mechanics and performance trade offs inherent in the different AIO modes, caching options, paravirtualization drivers, and thread settings. We will outline which OpenStack configuration options lead to the most desireable KVM/QEMU configuration settings, and what could be done to further enhance OpenStack's ability to take advantage of everything KVM/QEMU has to offer. Highlights of performance data will be shared that characterize how these settings affect real world MySQL workloads.

 


What can I expect to learn?

Learn about the internals of the KVM/QEMU IO subsystems, the perfomance implications of them, and how to configure OpenStack to deliver the best configuration for tenant virtual machines.
