Ganeti is a cluster virtualization manager providing simple, standalone and robust virtualization clusters using a bunch of commodity KVM or Xen hosts. It was initially developed inside Google but made available as Free Software in 2007 and has been included in Debian since Lenny. Since then, it has become a virtualization platform of choice for many companies and organizations around the world, among which the Debian Project itself. After a couple of years in hiatus, development is slowly resuming with the project being gradually handed over to the community. This talk aims to give a bit of background on Ganeti itself and describe the current state of affairs. It will highlight all present and future challenges, from community-driven development and project governance, to transitioning to present-day Haskell and Python 3 and supporting current hypervisor versions. System administrators and Python or Haskell coders looking for an interesting project to contribute to will feel at home with this talk. Most people interested in virtualization technologies will also hear a couple of interesting bits.

During this session we'll provide a quick update on the current status of the Puppet and PuppetDB packages. We will also discuss about Puppet's future in Debian and how people can help. Whether you're just using Puppet, or you would like to be involved in the Debian Puppet team, this BoF is for you!

In this talk, I would like to share our success story running skroutz.gr, one of Greece's most-visited websites, using Debian with over 400 installations covering every tier, from core routers, to servers, development workstations and support desktops. The prospective audience for this talk are primarily system administrators, but its scope is broad enough to include bits on packaging, contributing etc. The key points include: - Maintaining a relationship with Debian: how, when and what to contribute, how to get your sysadmins involved. - Sysadmin-friendly packaging in the age of Puppet: playing nice with both sysadmins and configuration management tools. - Internal repository organization and package versioning; how to make sure your own packages play well with Debian's. - Leveraging Debian's own automation mechanisms in a highly automated environment; taming d-i preseeding and putting dpkg-divert to good use. - Applying security updates semi-automatically on a fleet of 300 servers. - Using Debian on the network: highly available routing and firewalling, using multiple upstream providers. - What we could do in Debian to further ease adoption by SMEs.
