If I install the latest Guest Additions with VirtualBox 4.2.6 on Ubuntu 12.10 guest I'm not seeing the "building the shared folder module" message in my terminal. I think I should see this in order to have this component installed properly.
I've installed these packages:
linux-headers-generic and I ran
apt-get update from the terminal according to these tutorials:
- Installing Virtualbox Guest Additions and Shared Folders on Windows 7
- VirtualBox forums - HOWTO: Install Linux Guest Additions + Xorg config
I'm running Windows 7 64 bit as a host with Ubuntu 12.10 64 bit as a guest.
