Looks like a problem with trying to access a zisofs cd from dom1 using 
a kernel which doesn't understand that. Two things to try: 
  a) when you compile xenolinux-2.4.25 ensure that you have zisofs 
     support configured in, and/or
  b) check the config for dom1 to determine why it's trying to access
     the CD [which I guess may hold a 1.2 demo disk?] 

Note that in general you're better to just put an entire copy of the 
normal root filesystem [used by linux on its own, or by domain 0] onto 
a new partition for domain 1; trying to use the stripped down version 
of stuff on the demo CD is generally less sane.
