What is the difference between “Configuring Software Repositories” for the “:” and without?
For example I found VBox 3.2.0 in the “Package Search (webpin)” which pointed to “Virtualization” and not “Virtualization:”.
Should I have both configured in my “Configuring Software Repositories”?
I have “only” 32-bits. I do not know if that matters, but when I do YaST > Software > Software search (webpin) and type VBox in the search field, I get five results where none of them is VBox, let alone VBox 3.2.0.
Thus I am not able to see what you see. And I refuse to believe that “Virtualization” or “Virtualization:” is the full URL.
Type in virtualbox and you will get the hits.
This is the url’s I was referring to:
download.opensuse.org/repositories/Virtualization/openSUSE_11.2/
download.opensuse.org/repositories/Virtualization:/openSUSE_11.2/
One has the “:”
I clicked on both links you provide above. The first shows a repsoitory and the second gives an Error 404 (not found).
IMHO is is not that difficult to choose 
Don’t ask me why webpin offers you that one. Maybe it has some cache or so.

The actual URL is → http://download.opensuse.org/repositories/Virtualization:/
