Launch Your VirtualBox machine via Terminal $ VBoxManage startvm "name" Replace the tag "name" with the os which you prefer to run. This command will run your preferred os, without having you to open the VirtualBox and then selecting the os. Ex: [suresh@mercury ~]$ VBoxManage startvm "ubuntu" Waiting for the VM to power on... VM has been successfully started. suresh@mercury ~]$ -- Warm Regards, Tha.Suresh My experiences with Linux: http://thasulinux.wordpress.com
