Virtual Machine Rhel 6.5 mount installation disk ISO, and as a Yum source
============================================
Place the directory where the ISO file exists on Windows into the virtual machine share
Then under Linux you can find the auto-mount shared directory under MNT to see if you can see the ISO file
Then mount ISO file: Mount-o loop/mnt/xx/rhel6.5iso/rheliso
Cd/rheliso, see if you can see the Repodata directory

Modify the Yum repository to Base=file:///rheliso (that is, the top level directory of the Repodata directory)
Enabled=1 gpgcheck=0

Yum list; If successful, the package file is displayed
