Debian eth0, eth1, eth2, in Virtualbox or VMware Virtual machines when copying

uses udev. Udev handles mapping MAC’s to the appropriate /dev/(X) file. If you copy a Virtual machine, Udev will remember the MAC address of the old NIC. When you copy the machine, the virtual host usually generates a new MAC address for the .
Udev will assign the new Device to eth1, eth2, and so on. If you want to change your NIC assignments make Udev forget the old MAC.
In Debian 5 (lenny) it is in this file:

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

In Debian 4 (etch) it is in this file:

/etc/udev/rules.d/z25_persistent-net.rules

To apply changes in Lenny: “udevadm trigger” or “udevtrigger” (in Etch)

Debian 4.0r4 NIC bonding

Install package ifenslave-2.6.

apt-get install ifenslave

make sure the real NICs kernel modules are loaded automatically

modprobe --list | grep -i

edit /etc/network/interfaces to look like this:

auto bond0
iface bond0 inet static
address 192.168.1.59
netmask 255.255.255.0
gateway 192.168.1.1
up /sbin/ifenslave bond0 0 1
down /sbin/ifenslave -d bond0 0 1
broadcast 192.168.1.255

make sure to remove ALL of the lines refering to old eth0 or eth1 settings.

add the following lines to your /etc/modprobe.d/arch/i386:

alias bond0 bonding
options bonding mode=1 miimon=100 downdelay=200 updelay=200
