FUDCon Pune: My talk on ‘Linux Virtualization’
My second talk at FUDCon Pune was on Virtualization (slides) on day 2. While I had registered the talk well in advance, I wasn’t quite sure what really to talk about: should I talk about the basics of virtualization? Should I talk about what’s latest (coming up in Fedora 16)? Should I talk about how KVM works in detail? My first talk on git had gone well, and as expected for this FUDCon, majority of the participants were students. Expecting a similar student-heavy audience for the 2nd talk as well, I decided on discussing the basics of the Linux Virt Stack. Kashyap had a session lined up after me on libvirt, so I thought I could give an overview of virt-manager, libvirt, QEMU and Linux (KVM).
And since my registered talk title was ‘Latest in Linux Virtualization’, I did leave a few slides on upcoming enhancements in Fedora 16 (mostly concentrating on the QEMU side of things) at the end of the slide deck, to cover those things if I had time left.
As with the previous git talk, I didn’t get around to making the slides and deciding on the flow of the talk till the night before the day of the talk, and that left me with much less sleep than normal. The video for the talk is available online; I haven’t seen it myself, but if you do, you’ll find I was almost sleep-talking through the session.
To make it interactive as well as keep me awake, I asked the audience to stop me and ask questions any time during the talk. What was funny about that was the talk was also being live streamed, and the audio signal for the live streaming was carried via one mic and the audio stream for the audience as well as the recorded talk was on a different mic. So even though the audience questions were taken on the audience mic, I had to repeat the questions for the people who were catching the talk live.
I got some feedback later from a few people — I missed to introduce myself, and I should have put some performance graphs in the slides, as almost all users would be interested in KVM performance vs other hypervisors. Both good points. The performance slides I hadn’t thought about earlier, I’ll try to incorporate some such graphs in future presentations. Interestingly, I hadn’t also thought of introducing myself. Previously, I was used to someone else introducing me and then me picking up from there. At the FUDCon, we (the organisers) missed on getting speaker bios, and didn’t have volunteers introduce each speaker before their sessions. So no matter which way I look at it, I take the blame as speaker and organiser for not having done this.
There was some time before my session to start and there were a few people in the auditorium (the room where the talk was to be held), so Kashyap thought of playing some Fedora / FOSS / Red Hat videos. (People generally like the Truth Happens video, and that one was played as well.) These, and many more are available on the Red Hat Videos channel on YouTube. There was also some time between my session and Kashyap’s (to allow for people to move around, take a break, etc.), so we played the F16 release video that Jared gave us.
Overall, I think the talk went quite well (though I may have just dreamed that). I tried to stay awake for Kashyap’s session on libvirt to answer any questions directed my way; I know I did answer a couple of them, so I must have managed to stay up.
