As many of you know, I work at Google supporting the Ganeti open source project use within Google. I'm on the New York team that does certain functions and the Munich team is responsible for the open source project itself. Both are hiring, but this post is about Munich.

The developers in Munich are taking on some new and exciting work related to the Ganeti open source project. We have a vision of where Ganeti can go and need experienced developers to make it happen. If you are interested in working in Munich on an exciting and important open source project, please check out this job advert:

Most of the Ganeti project is in Python with some Haskell. Experience with C, C++ are also listed in the advert.

Lance Albertson wrote up a great description of how Ganeti Virtualization Manager performed under pressure during a power outage:

Nothing like a power outage gone wrong to test a new virtualization cluster. Last night we lost power in most of Corvallis and our UPS & Generator functioned properly in the machine room. However we had an unfortunate sequence of issues that caused some of our machines to go down, including all four of our ganeti nodes hosting 62 virtual machines went down hard. If this had happened with our old xen cluster with iSCSI, it would have taken us over an hour to get the infrastructure back in a normal state by manually restarting each VM.

But when I checked the ganeti cluster shortly after the outage, I noticed that all four nodes rebooted without any issues and the master node was already rebooting virtual machines automatically and fixing all of the DRBD block devices.

Ganeti is a management layer that makes it easy to set up large clusters of Xen or KVM (or other) virutalized machines. He has written a great explanation of what is Ganeti and its benefits too.

I use Ganeti for tons of projects at work.
