[ovirt-users] DevConf.CZ 2016 - my experience

Fri Feb 26 13:00:54 UTC 2016

Hello,

"Would be cool to support ARM based hosts running virtual machines!"

I would also be very interested in that.
I recently visited the Centos Dojo in Brussels and also came away with the
idea that the ARM road is very long.

This seems like an opportunity to ask:
this is not possible on any board right now?

I was thinking:

Hummingboard Edge

Greetings, J.

> On the first weekend of February I've had the pleaseure of attending
> DevConf.CZ 2016, which took place in the wonderful city of Brno, CZ.
> Compared to FOSDEM, it's a more relaxed, young and vibrant conference, but
> it was just as fun and rewarding from my perspective.
> Here's a disorganized personal summary:
>
> - Met community members as well as customers and Red Hat TAMs (Technical
> Account Managers) from all over Europe.
> - Attended a presentation on a research to understand theoretical best
> possible improvements to migration convergence performance[3]. I hope to
> see some of it in coming versions of QEMU, while we work on other
> improvements to this critical feature.
> - Attended a presentation on the status of ARM on Fedora and CentOS[14].
> Seems like a great positive effort, but the road is still long for complete
> support. Would be cool to support ARM based hosts running virtual machines!
> - Attended a presentation on native vs. threads implementation performance
> in QEMU[4]. The results were not conclusive, though some improvements in
> native brought it close to or better in some cases to threads. Seems that
> our default of heuristic for threads in file-based storage and native in
> block based storage is fine for the time being, but we'll watch closely for
> developments in this area.
> - Attended a presentation on debugging qemu (mainly) in OpenStack[5] - I
> think (and asked) if libvirt can do a better job - in saving in a cyclic
> log the QMP commands sent and the response from the guest and dump it in
> case of a guest crash.
> - Attended a Cockpit hackfest[9] - as we intend to use Cockpit as our UI
> for RHEVH Next Generation Node, it was great to present our use case and
> exchange thoughts, ideas and directions. Few bugs were filed during the
> hackfest per our comments.
> - Attended 'Dockerizing JBoss Applications' presentation[10]. Great work
> done by the JBoss team to improve and streamline packaging of JBoss into
> containers.
> - Attended 'Fedora Upstream Testing' presentation[13]. I disscussed with
> the presentor the possibiliy to run oVirt with Lago[17] in Fedora, in a CI
> way, by monitoring distgit changes for relevant packages (such as lvm2,
> device-mapper*, libvirt and others.
> - Attended 'High Performance VMs in OpenStack'[12] - looks like oVirt is
> already doing a lot of what OpenStack are working to achieve
> high-performance from KVM!
> - Preached on running Lago with OpenStack, Gluster and Cockpit. At least
> the first two items look really promising and I'm looking forward to a
> collaboration in those efforts. I might just try to do the Gluster one
> myself.
> - Having used the oVirt Live[18] USB DoK image in both FOSDEM and DevConf,
> I've found several items where we can improve in and filed relevant RFEs
> for them[15][16].
>
> - The oVirt team has delivered numerous presentations in the
> virtualization track[1][2][6] - and the Gluster team has additionally
> provided more presentations[7][8], which were all well received.
>
> I'd like to thank Red Hat's OSAS team members Mikey and Brian for once
> again, just one week after FOSDEM, leading the effort of representing the
> oVirt project and community in this event.
