Images and Snapshots


Images are files that contain a bootable operating system, e.g. Linux derivatives. Each of the different compute center provide a selection of Images you may use to boot up a virtual machine. If you want more behind-the-scenes information, please visit the respective wiki page.

X2Go Image

X2Go Images allow you to start your own desktop in the de.NBI Cloud which you can access from any operating system (Windows, Linux, MacOS).


Please note, that as an alternative we now offer Apache Guacamole.
