Finally, I was able to configure OEL 7.3 Minimal Install.
OEL 7.3 was a challenge since NAT and Host Only Networking from VirtualBox was not working.
I broke down and ended up using Bridged Adapter.
Next, blogs out there were using Server with GUI installation which is a really bloated option.
Even tried CentOS 7.0 Gnome and did not like having to install UEK or rebuild RPM.
Did it work?
Will you try it and let me know?
