Which versions? It'd really help if you provide such information early. 
It would eliminate guesswork wasting everyone's time.

With the information you provided so far it's plain impossible to figure 
out what's going wrong. At the very least I need the resulting medium 
registry entry in VirtualBox.xml, and the reason why it is marked as 
inaccessible. You can either query the last error message for the medium 
through the API or go to the Virtual Media Manager in the GUI and hover 
over the entry which shows the trouble - the info popup will contain the 
error message.
