uniVM - virtual machines for institutes

The Hochschulrechenzentrum offers virtual servers (VM) for use by institutes and facilities of the University of Bonn for the fulfillment of university tasks (research, teaching, administration).

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

Setting up a VM as part of the uniVM service also includes switching the virtual network adapter into an isolated private VLAN, in which direct communication between different VMs is prevented for security reasons. An IPv4 and an IPv6 address are automatically assigned statically when the VM is created.

If communication between several virtual servers within the institute is required (e.g. web access to database servers), a private VLAN in community mode can be requested via the application form or later via the contact address given below. In addition, an individual network can also be planned and created. The latter is associated with additional costs.

Standard ports for web server, SSH and RDP are accessible from BONNET. Further activations can be applied for directly via a form integrated into the portal or by e-mail.

Users have the option of managing VMs via the self-service portal provided (resource adaptation, creation of a snapshot,...). Everything from the operating system level of a VM is the responsibility of the service provider (user). The user has full access to the guest operating system and is responsible for the maintenance of the operating system, security measures and the correct licensing of the installed software (see application form).

VM backups are created daily at the storage level (NetApp storage snapshot), stored for 7 days, and can be restored to the original VM upon request.
Note: This type of backup is not a disaster recovery backup, the data is not moved to another location. A disaster recovery backup of the VMs is not centrally implemented at the moment and must be implemented by the operator of the VM if required (e.g. via backup/TSM).

The application for access to the self-service portal for an institute is made via an application form. A PSP element is required for billing the cost sharing.

We have collected further information in a Wiki. There you will find instructions for the management of the 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.
