[Users] Rebooting node causes re-arrange of nic interfaces.

Every time i reboot one of my nodes eth0 eth1 and eth2 gets re-arranged, this really messes with the network configuration. I am running the ovirt-node 2.3 iso image. I havent had this issue with earlier installs of debian/fedora etc. any way to fix this besides getting new hardware? Cheers Espen
