snf-image is the secure image deployment tool used by the synnefo’s Compute Service, cyclades.
Currently, it is implemented as an OS definition for Ganeti.
Furthermore snf-image acts as a standalone add-on for Ganeti and can be used with it independently. Someone who uses Ganeti, (and has nothing to do with Synnefo) can use snf-image to serurely deploy many kind of images with Ganeti.
Please refer to the snf-image documentation for all details concerning installation and configuration.
