Sorry, I don''t know exactly how to do it. Could you elaborate on how to
manually configure eth0?

Thanks for pointing out the custom mac address question.

Can anyone tell me about these error messages from xend-hotplug.log

xenstore-read: couldn''t read path backend/vbd/5/777/physical-device
xenstore-read: couldn''t read path backend/vif/5/0/ip
xenstore-read: couldn''t read path backend/vif/5/0/bridge
xenstore-read: couldn''t read path backend/vbd/5/777/physical-device
[After I shutdown the domain I further get]
xenstore-read: couldn''t read path backend/vif/5/0/ip
xenstore-read: couldn''t read path backend/vif/5/0/bridge
interface vif5.0 does not exist!

I think "couldn''t read path backend/vif/5/0/ip "  should
really have to do
with this IP problem. But I don''t understand which path is this? Is it
a
path somewhere on root file system?
