How to run 2 linux system at the same time via RosettaVM?

[muyuka]

I installed ubuntu via RosettaVM and it works perfect. Also I want to run another ubuntu at the same time. But when I try to open new rosettaVM, it brings the ubuntu screen which is already opened. Is rosettaVM supporting to run more than one server at he same time? Also I wonder that how can I change images. I mean, for instance, an ubuntu server is running but I don't want to use it anymore, and how can I change it with another iso. I am asking because, I couldn't find any interface about these.

Thanks for this great project. I really loved it.
