I think I was lucky vbox didn't crash on me (or didn't care enough), but the kernel modules vbox uses and which I compile w/ # /usr/bin/vboxbuild need to be recompiled at that point. The modules I use are vboxdrv and vboxnetflt, there might be one more or so. also important when we're supposed to help you would be if you posted your error messages by pastebin or screenshot or whatever, actual screen photo. cheers! mar77i
