Hi,
Thanks for hellp. I think that's the problem of my setup file. So I
changed my setup file, andthe system give me a new problem:
Here is what the console dumps:

My xmdefconfig file and fstab file on /mnt/etc:
hda1 is my boot partition. Before I ran the #xm create command , I
had losetup /dev/loop1 /dev/loop2 to some disk partitions.
Here is my fstab file after mount loop1 and loop2:
/dev/sda2 / ext3 defaults 1 1
/dev/sda1 /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
