If possible, Can you create virtual Machine for Qliksense / Qlikview Server. I never tried this but by help of VMWare may be possible with in the single AMI Machine.
I have installed Qlikview / Qliksense for development but i haven't done Sense server as of now. Could be possible. If not, May be use Another server for QS server(try to explain same issue with admin team they may arrange for you)
