For some reason, several people have told me that they are not getting the link to download the Virtual Machine Additions for Linux on Microsoft Connect anymore. If that happens to you, try the direct link: https://connect.microsoft.com/content/content.aspx?ContentID=1475&SiteID=154 . You will still need to enter your Passport Live ID in order to access the Connect website, but that link should take you directly to the Linux Additions page.
