First comment I have doesn't answer your question but might help with your end goal: Circuit Design Suite now has a free online component that works on Linux (and anything else you can get to connect to the internet) for analog circuit simulation. No it can't do any data acquisition with your NI ELVIS but if you just need analog simulation then it will do the job: beta.multisim.com
As you are probably aware, the NI ELVIS is not supported nor garuneeted to work on virtual machines running linux. However, I have seen someone using Oracle's VirtualBox to successfully communicate to the NI ELVIS so it might work. My best recommendation: try it out. It won't do any harm to the NI ELVIS and I'm interested in hearing the results.
