you should set a mac address in your domU config file.

e.g.
vif = [ 'mac=00:00:cb:62:fd:7f,bridge=xenbr0' ]

otherwise the interface changes it's mac every time the domU is brought up.

Thanks. That worked. I let the machine boot, copied the assigned MAC to the .cfg file, and it started configuring eth0 automatically after the next boot.

I'm still curios to understand what actually goes there, does the "Checking for hardware configuration changes" boot stage do the renaming?
