I have installed virtualbox-ose on ubuntu 11.04 and windows XP pro as the virtual machine. Now I want to have a shared folder which can be accessed on both, the virtual machine, and my XP guest machine.
How can I do that?
First step is to install Guest Additions in your virtual Windows.
You have to install the Virtualbox Guest Addition (GA) to be able to share with the host if using Windows.
First create a folder to share in with the host. For example, create a folder called X in your Host's Desktop and before or after installing the Guest Addition right click on the guest os in your Virtualbox main window. Go to settings and look for the Shared Folder option.
Select it and choose the X folder you just made. Now boot the guest OS with the Guest Addition already installed (if you haven't installed it yet do so) and on the terminal type
For Linux is easier.
