Comment 4 for bug 1429614

The sync was done in LP: #1433678.
I don't think this is worth an SRU, as noted in comment 9 of the aforementioned bug, upstream already have the following in their packaging:
Conflicts: virtualbox, virtualbox-guest-additions-iso, virtualbox-ose
Replaces: virtualbox
Provides: virtualbox

I don't think there is anything we can do about file conflicts in cases where a user installs virtualbox from the .run installer or builds from source.
