I tried to reproduce this bug and the possible fix. After inserting a valid installation CD (tried with a Windows NT and a Debian Wheezy CD), Gnome Boxes does not indeed propose to use this install media in his "Source Selection Screen"
Installing the libosinfo-bin pacakge does not help, altough libosinfo itselfs correctly detects the CD to be an install media. /usr/bin/osinfo-detect /dev/sr0 Media is bootable. cat /etc/apt/sources.list deb http://debian.inode.at/debian wheezy main contrib non-free deb http://security.debian.org/ wheezy/updates main contrib non-free deb-src http://debian.inode.at/debian wheezy main contrib non-free -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
