Hi All,
after go stupid for 2 days I kindly asking if is possible to install VirtualBox onto CentOS 7,
if is possible I kindly ask if there is a guide where is CLEAR how to make understand Virtualbox that the needed headers and kernel are CORRECTLY updated and CORRECTLY installed
always thanks

The only available guide that I know of is the User Manual. It might not be fancy with graphics and animation, but it's accurate.

It looks like you are really saying the install fails because VirtualBox is telling you that the kernel and headers are not correct. Run the two following commands in a terminal on the host and report exactly what they state:
It would also help if you posted the /var/log/vbox-install.log as an attachment here as well.

I have VB running on CentOS 7 without issue.. Post your actual error.
