LinuxCon Europe 2011 in Prague is coming

And we are coming to Prague, too! This time, there will be as many as six people and two talks from us, plus we will held a memory cgroup controller meeting.

The following OpenVZ/Parallels people are coming:

  • James Bottomley, Parallels virtualization CTO
  • Kir Kolyshkin, OpenVZ project manager
  • Pavel Emelyanov, OpenVZ kernel team leader (he's also taking part in Linux Kernel Summit)
  • Glauber Costa, OpenVZ kernel developer
  • Maxim Patlasov, OpenVZ kernel developer
  • Andrey Vagin, OpenVZ kernel developer

Two talks will be presented. Since linuxsymposium.org site is currently down, let me quote talk descriptions here.

1. Container in a file by Maxim Patlasov.

One of the feature differences between hypervisors and containers is the ability to store a virtual machine image in a single file, since most containers exist as a chroot within the host OS rather than as fully independent entities. However, the ability to save and restore state in a machine image file is invaluable in managing virtual machine life cycles in the data centre.

This talk will début a new loopback device which gives all the advantages of virtual machine images by storing the container in a file while preserving the benefits of sharing significant portions with the host OS. We will compare and contrast the technology with the traditional loopback device, and describe some changes to the ext4 filesystem which make it more friendly to new loopback device needs.

This talk will be technical in nature but should be accessible to people interested in cloud, virtualisation and container technologies.

2. OpenVZ and Linux kernel testing by Andrey Vagin.

One of the less appealing but very important part of software development is testing. This talk tries to summarize our 10+ years of experience in Linux kernel testing (including OpenVZ and Red Hat Enterprise Linux kernels). Overall description of our test system is provided, followed by details on some of the interesting test cases developed. Finally, a few anecdotal cases of bugs found will be presented.

In a sense, the talk is an answer to Andrew Morton's question from 2007: "I'm curious. For the past few months, people@openvz.org have discovered (and fixed) an ongoing stream of obscure but serious and quite long-standing bugs. How are you discovering these bugs?"

Talk is of interest to those concerned about kernel quality, and in general to people doing development and testing.

Finally, there will be a memcg meeting. Since LinuxCon will be right after the Kernel Summit, a number of kernel guys will still be there so anyone interested in cgroups can come. This meeting is a continuation of our recent discussion at Linux Plumbers (see etherpad and presentations).

See you all in Prague in less than a month!

I would like to be there, but it's a bit to far ( by car ~600km) :-(

You mean, will it be possible? I don't know, check the conference web site. I hope so.
