Problem handling
Ifup eth0 indicates that the network card does not exist.
Restart after / etc/udev/rules.d/70-persistent-net.rules deletes excess Nic entries
Ifconfig has no bond0 display
Deactivate the NetworkManager service and return to normal
Service NetworkManager stop
Chkconfig NetworkManager off
