Anthony why networkmanager is installed in zenlb2? Did you install it?
Zen service manages interfaces and farms and networkmanager is not
installed by default so this zen is modified and other services are
managing the system in place of zen.
Also your attached logs show a dhclient is executed and this also is
disabled by default...
