OSFarm allows the dynamic creation of Xen virtual machines (VM) of Linux distributions, currently supporting SLC3 and SLC4. These VMs can have add-on packages installed like gLite packages, such as gLite-CE and WN. OSFarm supports multiple architectures, and images can be created either for deployment over LVM volumes or file based VDBs.

Created images are automatically added to the repository after completion from where the user can download them.
