As I understand it, you have asked NM to manage your ethernet connection
(in /etc/sysconfig/network-scripts/ifcfg-em1).
I believe that NM over-writes /etc/resolv.conf if it cannot establish
the specified connection.
In my opinion this is silly; but that is what NM does.

If you don't want NM to manage your connection you should say so
in the above ifcfg file.

Or at least that is my understanding of the setup.
