I found it in /etc/udev/rules.d/30-persistent-net.rules
This file include the following lines

SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:16:3e:00:00:12",
ib/udev/rename_netiface %k eth0"
SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:16:3e:00:00:d5",
ib/udev/rename_netiface %k eth1"

Eth0 is the old network interface which i find also in Yast.
I think eth1 was automatically added by xen from the config file but i
find it in Yast and (see on the top) the os also find it.
Should i changed something in this file?
