I ponder packaging ganetimgr for Debian at some point, but at the moment I am struggling here and there to get it fully online without too many exceptions being raised.
I also plan to translate ganetimgr to German.
Furthermore, we (the Arctica Project, a new remote desktop solution for Linux servers) plan to provide a VDI solution inside the Arctica code base.
At the moment, ganeti feels most appropriate for managing VDI instances.
about myself: I am a Debian Developer, used to be X2Go release manager, member of the MATE project (my team packaged MATE for Debian), I have recently founded my X2Go follow-up project: the Arctica Project.
I will wait here for some more time, otherwise contact you via the ganetimgr issue tracker.
