---an item in /var/log/syslog :

kernel: [ 6.949035] udev: renamed network interface eth0 to eth1

---an iten in /etc/network/interfaces :

auto eth0

Probably because you changed the mac address. Original eth0 remains with
the original HW address and the "faked" one is detected as a new device
(eth1).

Take a look at /etc/udev/rules.d/70-persistent-net.rules and verify that
the rule for your card (check its MAC) is consistent with the naming
scheme you want.

You can easily edit that file or even remove it if you want to
regenerate it from scratch.

good luck

The problem is solved by
editing /etc/udev/rules.d/70-persistent-net.rules

Thanks for all the help from the maillist.
