I am testing Ubuntu Yakkety server amd64 iso: http://cdimage.ubuntu.com/ubuntu-server/daily/20160924/yakkety-server-amd64.iso. On a Virtualbox VM, you start server installation from CD ROM, after selecting keyboard layout installer starts to detect and mount CD-ROM, but fails to detect it, when asked to retry mounting the CD-ROM, if you select yes it keeps on looping asing this question, if you select no you get a "Detect and mount CD-ROM installation step failed". And cannot carry on with server installation. I checked and the ISO image is selected as virtual optical disk file in the storage settings of the IDE controller.
