You're right.  I found my solution removing the MAC address.  Now the
problem disappears.

Sorry I read your advice wrongly.  Actually I need to duplicate both
disk.img and swap.img.  Instead of starting the guest just mount the
disk.img and edit the files on chroot environment.  One disadvantage, I
can't execute problem on chroot environment.  E.G. after editing
/et/hosts I can't run /etc/init.d/hostname.sh to take effect.  Nor to
run;

# hostname
and
# hostname -f

to check the output.

Thanks.  I'll test it on next Xen box.
