How to get RHEV-M to see a physical CD

I am installing a windows 2008 server VM.

As this is a one off install, I am putting the media in the DVD on the server and installing from there.

Unfortunately, when I right click, run once, click "attach CD"   no media appears in the window to select.

I tried putting the media in the data center and putting it in the RHEV-M server

I RTFM on the portal and it assumes the RHEV-M can populate the media field.

Of course I googled it, and found nothing.

I searched redhat and found nothing.
