Virtual machines for institutes - uniVM

The service includes the provision of virtual machines based on predefined templates (CentOS, Ubuntu, Debian, Windows Server), against a cost contribution (breakdown in the application form), which can be requested with the help of a self-service portal by the user appointed by the institution. The templates contain an operating system in minimum configuration and with settings optimised for VMs. The size of the VM (CPU, RAM, HDD) is freely customisable by the user within a predefined framework and determines the costs per VM.

For whom?

Institutions and facilities of the University of Bonn

This service is available to institutions and facilities of the University of Bonn. Requesting access to the self-service portal for an institute is done via an application form. A WBS element is required for the settlement of cost sharing.

What for?

Management of the VMs

    Users have the possibility to manage VMs via the self-service portal provided (resource adjustment, creation of a snapshot,...). Everything from the operating system level of a VM is the responsibility of the service operator. They have full access to the guest operating system and are solely responsible for the maintenance of the operating system, security measures and the correct licensing of the installed software (see application form).

    Backups of the VMs are created daily at storage level (NetApp storage snapshot), stored for 7 days and can be restored to the original VM on request.

    Please note: This type of backup is not a disaster recovery backup, the data is not swapped out to another storage location. A disaster recovery backup of the VMs is currently not implemented centrally and must be realised by the VM operator if required (e.g. via backup/ISP).

    How does it work?

    We have collected further information in a wiki. There you will find, among other things, instructions for the management of virtual machines including the increase of resources (CPU, RAM, storage), the change to the community VLAN, as well as an overview of the configuration of the templates.  

    If you have any questions, please write to vhrz-support@uni-bonn.de.


    We always carry out maintenance work (patchday) on the uniVM service on the first Wednesday of each month between 08:00 and 12:00.


    Detailed information and instructions can be found in the HRZ-Doku.
