5. Check the cd-rom file at the destination host.
[root@lxlcompute1]# cd

-rw-r--r-- 1 root root 1928 Feb 23 10:28 libvirt.xml
6. Mount this cd-rom file to a path, and view it's content at the destination
host.
[root@lxlcompute1 122e21e1-6f9a-46ce-835a-a05a4e5f5c95]# mount -o loop
disk.config /home
mount: /dev/loop0 is write-protected, mounting read-only
[root@lxlcompute1 122e21e1-6f9a-46ce-835a-a05a4e5f5c95]# cd /home/openstack/
[root@lxlcompute1 openstack]# ll

dr-xr-xr-x 2 root root 2048 Feb 23 10:15 2012-08-10
dr-xr-xr-x 2 root root 2048 Feb 23 10:15 2013-04-04
dr-xr-xr-x 2 root root 2048 Feb 23 10:15 2013-10-17
dr-xr-xr-x 2 root root 2048 Feb 23 10:15 latest
7. We can see the problem, the folder named "content" is missing.
This disk.config file is a new and empty cd-rom file.
