KVM Forum Day 3

Slides for the presentations.

Keynote - Migration failures

All the things that can go wrong with migration. Good hints about how to make driver state more robust between versions. Issues about CPU versions.

Slim down QEMU

Very interesting talk from Marc André, with an idea to off-load some components of the VM to external processes. Makes sense for things like GPU for both bad reasons (e.g. big bad lock in QEMU, so can't compile shaders) and better ones (e.g. running the VGPU process on a core that is better suited for that in bigLITTLE-style configs)

Applying polling techniques to QEMU

Slides are here.

New disks are much faster than they used to be. Shows numbers about 2017 SSDs reaching in the order of 500K IOPS. Used to be what you'd get from a SAN.

This is the work blog of Christophe de Dinechin for Red Hat. Think of it as a public lab book.

This should not be particularly interesting except to myself. It's really more intended as a set of personal notes, so there is no formatting whatsoever. I type tings as I go along during the day. All you'll find here are things like stack traces, Linux commands I want to remember or bugzilla links I want to be able to return to.

If you want to read stuff about my work at Red Hat that I believe is more interesting to the general public, you will find it on A Spice Odyssey. If you want to read my rants about everything else, go to Grenouille Bouillie. This is about as much advertisement as you will find on this site.
