I've just got a few questions about virtual machines, for one do you need all the system resources for both operating systems? I'm just playing around with it right now, getting used to it, so I'm installing another Ubuntu in the virtual machine and I'm noticing my computer going a bit slower with some pauses.

Is it possible to transfer files between the virtual machine and your...main pc...?

Thats about all I have for now, it really cool that you can have another operating system running inside your main one!
