Disable auto launching, make VirtualBox work with iTunes 9.2

Disable applications from launching automatically:

On Ubuntu 10.04, this setting can be changed in the preference window of Nautilus. See the Media tab.

Make VirtualBox work with iTunes 9.2:

ps. How to show all the USB devices dimmed in grey

Enable VT-x/AMD-v in settings of Virtual Machine. Reboot, enter the BIOS, find Virtualization tab, enable Virtualization extension. Then it will Boot Then, TURN OFF the PC - Turn on again. (Don't reboot, turn the PC off. I don't know what is exactly different, but rebooting doesn't seem like turn on the virtualization function.)

Now launch VirtualBox and run the virtual machine. Go to /home/user_name/.VirtualBox/Machines/virtual_machine_name/Logs, then open VBox.log file. Search the word "VT-x". See if it reads as activated. If it is successfully enabled, you're good to go with iTunes 9.2!
If you don't have virtualization function in your BIOS, then it seems worth to install VMWare. But it seemed quite complicated to install it on Linux.
