Please attach the VBox.log file of that virtual machine. I assume that your CPU does not provide support for VT-x. In that case your VM will not start because you set 2 guest CPUs. Running VMs with more than one guest CPU requires VT-x support according to the VirtualBox documentation (section 10.3).
