You can manually force the assignment from a network card to what device comes up as (eth0, eth1 ...), you can manually edit this file:

           /etc/udev/rules.d/70-persistent-net.rules

This maps MAC address to device name. Example:

{{Code|

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1d:60:b5:43:66", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="5c:d9:98:af:21:43", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="et1"}

Please exercise care. Improperly modifying this file may render your system without network or even not boot properly.
