Hi

I just installed Virtualbox and would like to try many other Linux OS's and I have a few questions.

1. How many OS can I install, If I only run 1 at a time?
2. Can most be installed via 2GiB usb stick/flash drive?
3. Does anyone have any links to a thread where they talk about this?
4. How difficult is it to get rid of?

I have 2GiB of RAM & about 80GiB free on Ubuntu, and dual boot Vista.

5. Should I give more than 512MiB for RAM to the guest OS?

Thanks
Dave
