I am happy to report that running VirtualBox 4.3.2 r90405 that this is now working again for me in Ubuntu 13.10. I was even able to get the auto mount on boot to work by adding the line to the rc.local file at the end.
I reference my saved bookmark for how to setup shared folders at the end is how I set the auto-mount up. http://www.giannistsakiris.com/index.php/2008/04/09/virtualbox-access-windows-host-shared-folders-from-ubuntu-guest/ Thanks to Ingo for the good advise, because VirtualBox 4.2.x told me it was entirely up to date -- I would have never guessed there was a 4.3.x -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1239384 Title: Unable to access shared folders in Virtualbox from 13.10 guest.
