VirtualBox'd
WIN7 Host
Ubuntu 12.04 LTS Guest

I have 2 wireless cards. I have 1 card connected to a public internet connection, this is the guest Ubuntu virtualbox. The other card is connected to my homegroup. I want to share E:\downloads from the windows host to my virtualbox.

I have shared the folder from shared folder settings in virtual box. I can see it at /media/sf_downloads but when I try to access it is says that I do not have permission. Any ideas?
