6.3.3 Copying the DVD contents
Copy the contents of the ISO image to the file system. Temporarily mount it over a new
directory tmp/ using a loopback device:
# cd /nfs
# mkdir tmp
# mount -o loop rhel-server-6.0-s390x-dvd.iso tmp
List the contents of the mounted ISO image:
# ls tmp
EULA README-pa.html RELEASE-NOTES-ml.html
eula.en_US README-pt_BR.html RELEASE-NOTES-mr.html
generic.ins README-ru.html RELEASE-NOTES-or.html
...
Make a new directory, /nfs/rhel6/, and recursively copy the contents of the DVD to it with
the cp -a command. This will take a number of minutes to complete. Then unmount tmp/
# cp -a tmp/* rhel6/
# umount tmp
Important: With RHEL 5, building a new repository for yum was necessary. With RHEL 6,
this step should not be necessary as the repository on the ISO image is correct. However,
this short section from the previous book is left here for reference.
For the yum command to work, a common metadata repository must be built with the
createrepo command. There is a sample repository in the directory Server/repodata/.
The group XML file named comps-rhel5-server-core.xml should be used to create group
information:
# cd /nfs/rhel5/Server/
# mv repodata/ repodata.orig
# createrepo -g repodata.orig/comps-rhel5-server-core.xml .

The newly created repodata/ directory contains the correct common medata:
6.4 Enabling the NFS server
The method of enabling an NFS server will differ depending upon the operating system.
However, the steps are basically the same:
► Export the appropriate directories.
► Start the NFS server in the current run level.
The directories to export with NFS are set in the /etc/exports configuration file. Export the
directory /nfs/rhel6/ to make the install tree available and /nfs/virt-cookbook-RH6/ to
make the files associated with this book available. First make a backup copy of the file. Then
edit the original copy and add the two directories as follows:
# cd /etc
