This installation guide works fine for me: http://www.lab128.com/rac12_installation_using_vb/article_text.html#download_software

Hello Team,

This article with bridged network with 2 primary adapters is not working fine for internet connectivity and due to which I couldn’t proceed with installation guide, However I found another related article with RAC 12c release 1.

I’m working with this thread as I have similar issue with Virtualbox : https://forums.virtualbox.org/viewtopic.php?f=6&t=81701

I got the actual issue now. When I tried to mount and run guest add ons my installation did not continue with building main guest addition modules and prompted to exit from terminal in Oracle Linux 6 VM.
