Updated to 2.2 (Win 32bit). Lost my Internet connection inside the virtual machine.
Temporary solution found at http://www.virtualbox.org/ticket/3655. There is a dll (in a zip) - post towards the end (2009-04-15 18:20:43 changed by frank) that fixed the issue. (though virtualBox lost the connection when I restarted the computer after I sent it into hibernation.
Indications that this will be repaired in a patch to 2.2 in the "near" future!
