As I stated before, with PV domUs, it doesn't matter what you call the devices in the domU config or /etc/fstab as long as you're consistent between the two.  PV domUs use the Xen VBD driver, not IDE or SCSI drivers, to communicate with the block device, so it doesn't matter if it's hda, xvda, or sda - it will still use the xenvbd driver and should work, as long as your configs match.

Are you using paravirtualization or hardware virtual machine (full virtualization, HVM)?

If i create domu for example with xen-tools (etch). There is something 
like this in .cfg file

root        = '/dev/sda2 ro'
disk        = [

Ok, there have to be no different between this entry and fstab in domu. 
But i remember, i can use sda in domu cause this is standard, i think. I 
think too there are a lot of users they take sda als device name. I cant 
find the mistake.
