Hi developers,

After an invitation from Radosław, I join the VDI discussion as well. 
I'm one of the authors of the OpenStack VDI paper [1] mentioned by 
Radosław. The paper is now freely accessible to everyone in the 
pre-published version [2]. Thank you Radosław for sharing.

The main repository mentioned in the OpenStack VDI paper is currently 
hosted on GitHub [3] and contains configurations for general testing and 
development purposes (for me and my colleagues). The repository also 
provides a little DevStack setup for some simple VDI tests based on the 
functionality that OpenStack already provides. If we aim for a more 
active development in the future, we can also move the repository to 
another more official location.

Our needs for a VDI solution are already outlined in our paper [1]. We 
are currently hosting part of the bwCloud [4] infrastructure and a HPC 
cluster [5]. Researchers and students can carry out computations there. 
However, we are receiving more and more requests from these people to 
offer virtual (powerful) graphical desktops for graphic(-intense) 
applications, so that computation results can be visualized or other use 
cases can be covered (e.g. office work). That's why we've had the idea 
of a free VDI solution for a long time, where we now (hopefully) 
initiated a further development with our published paper.I'm looking 
forward to further exciting ideas and a great cooperation with all 
interested people from the OpenStack community.
