The problem is udev - check:
cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, probably run by the persistent-net-generator.rules rules
file.
#
# You can modify it, as long as you keep each rule on a single line.
# PCI device 0x11ab:0x4363 (sky2)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:a0:d1:78:99:70",
ATTR{type}=="1", NAME="eth0"
Just rename your devices here to get eth0 as wanted. The Problem is, if
you _do_ not explicitly define a mac-address in domu-cfg, xen will
generate one on each startup of the domu, so your nic will become eth99
on the 98th startup ;)
