OS Farm

OS Farm is a repository and a tool for OS images that can be used in Xen Virtual Machines. It creates minimal root file systems of SLC3 and SLC4 and allows addition of individual Yum packages and gLite services. Images can be created for i386 and x86_64 architectures, and the images are available in both raw images and tar files. The former format allows the image to be utilized in Xen directly after download.

OS Farm keeps a repository of the created images. If a requested image configuration already exists in the repository, it is not recreated and can be fetched directly from the repository.

The python scripts, slc3_generator.py and slc4_generator.py can be used directly in a shell to generate images locally.
