                please find some config files below. I did the interface
                config only through the oVirt GUI.<br>
                <br>
                I mean by reordering that after every reboot some
                interfaces are not the same as before. That means I need

                              <br>
                              I have two nodes (running CentOS 7) and
                              the network interface order changed for
                              some interfaces after every reboot.<br>

                              The configurations are done through the

                              configured automatically by VDSM.<br>
                              <br>
                              Is there any option to get this configured
                              to be stable?<br>
