Hello to everyone I'm a new italian member so I'm sorry if my english isn't perfect. I was thinking... Why not (in CentOS 7) insert a tab in the installation phase that can permit an automatic installation of guest's additions tools (I'm using virtualbox, but it can be applied to other platforms with a menu), a little system that reveals the guest addition's cd and if isn't inserted, displays to the user a message with informations about how insert it and do the installation automatically? Thanks for all of people that want to reply, I know that this virtualization platforms are in part in discordance with the ethical free software's mindset...but why not in centos, with proper informative messages? Good afternoon Raving
