This level of information is not very useful. I do all these things all the time, and I don't have problems. On the other hand, if you're having problems, I'd like to know why. Take a look at http://www.vinumvm.org/vinum/how-to-debug.html and supply the appropriate information. That way we have a hope of solving the problems. FWIW, most problems I've seen with Vinum have been pilot error.
