I'd check the location of you've copied the two files -- it
sounds a lot like they've ended up in root. Have you got a
separate /boot partition per chance? I think the standard Grub
documentation should help you.

Hmm, that's not good. 

Unless you have a serial port connected, you might want to remove
the ser_baud line from grub.conf. Also, you might want to add the
'ignorebiostables' to the 'kernel' part of the grub.conf, just in
case Xen is getting confused by your hardware.

Can you tell us a bit more about your system? e.g. CPU(s),
chipset, SCSI card, network card etc.
