Seeing as how VMware wants to charge $50 regardless of upgrade or new user, and I don't want to pay for that, I want to move to VirtualBox. How would I go about this process? My VMware virtual image is on a Lion hard drive and I am trying to move it to a new 2012 MBA that I will instal VirtualBox on. Is there anything I should be weary of before I install VirtualBox? Can I change how much RAM I give the VM later or is it set in stone? --- EDIT: If there is a way to get VMware Fusion 4 working on Mountain Lion, that would be helpful as well. I am just running a Windows 7 VM.
