When copying a vmware image with a debian guest os, the mac adress changes, and the next nic is called eth1.
To fix this, remove the old declaration and replace it with the correct one in:
/etc/udev/rules.d/z25_persistent-net.rules
Example:
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM==”net”, DRIVERS==”?*”, ATTRS{address}==”00:0c:29:93:2f:3c”, NAME=”eth0″
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM==”net”, DRIVERS==”?*”, ATTRS{address}==”00:0c:29:fe:01:76″, NAME=”eth1″
