Where are located files for Hardware Network configuration ?

Hi,

I am using virtualization. Guest and Host are Fedora 14

When I've got the image running, I've got on my image :
Hardware xxxx associated to Eth0

Now, if I back and restore the image on a different machine.... The hardware
which is the same, most of the time, is associated to eth2 or eth3

The problem is that I cannot start by : service network start
It cannot find eth0 !!!

Where is located the file ( on Fedora 14 ) saying that I have such hardware
, associated to ethX ?

Thanks for your help

Thats not only true for different virtual machines it happens even on
new hardware. udev ist detecting a new network card and creates a new
entry in /etc/udev/rules.d/xx-persistent-net.rules keeping the old eth0.
If you remove this file before booting on the new machine it should word.

The hardware for eth0 is gone :-).

/etc/udev/rules.d

Hi Kurt,

Thank you foryour reply.
I had a look in my Fedora ( /etc/udev/rules.d ) , but I can't find any info
in this folder.

I have some files like :
* 10-Vboxdrv.rules
* 40-hplip.rules

But nothing concerning "network" !?!?
