Ah, ok, sorry, missed the connection there. 

That makes sense. /dev/root is a "symbolic link", which probably doesn't
exist in your /dev on the DomU "disk"... You may be able to achieve the
same thing by "ln -s /dev/sda1 /dev/root" before the mount command. (I
never get the arguments for ln right, so they are probably supposed to
go the other way around!)
