I created a virtual box of Ubnutu 12.04 64 bit, installed on a host with the same system.

I installed VirtualBox Guest Additions on the guest, and restarted the guest.

However, when I try to open "shared folder" on the guest, I still get a message saying that "VirtualBox Guest Additions are not available", and when I look at /media on the guest, I don't see the shared folders..

I tried to install VirtualBox Guest Additions again, and restarted the host and the guest again, but I still cannot access the shared folders.

Any suggestions?..

  • Turns out this was a bug in the VirtualBox version available from the software center (4.1.12)... problem was solved after I switched to the latest VirtualBox version from the Oracle site (4.2.16) Commented Jul 18, 2013 at 11:59

    yeah - an upgrade to latest version always is a good idea. :)
