Ganeti cloud init

Nightfly19 created a ganeti os definition based on our work with images last week. It is available now from

This is a simple wrapper that lets you use images with ganeti virtual machines. This is huge because you can use prebuilt images from operating system vendors. Most OS distributions are crawling over each other trying to provide openstack-capable images. Now these images and convenience are available to the ganeti world.

From the readme:

The advantages to installing virtual machines from cloud images are:
  • Speed: This is much faster than using PXE boot or cdrom boot to load virtual machines.
  • Consistency: These images will be identical to amazon AMIs or machines running on an openstack cluster.
  • Lower effort: The OSUOSL Ganeti-instance-image project can produce a similar effect, but requires the administrator to provide their own dump/image files. These images can be pulled from the internet.

We hope to improve the functionality and installation instructions in the next couple of weeks. But for now, we'd love for some other ganeti users to try it out and let us know if it works in your environment, and what we can do to make it more generally usable.

  1. just gave this looks good! i guess you will probably want to package it up as rpm and debs next. this is far more convenient than cooking up home brew images.
