At the very least, I consider this a bug and have reported it as such:
https://bugzilla.redhat.com/show_bug.cgi?id=508865

I suspect this is the result of trying to use SELinux to protect everything 
and the mandatory access control idea that everything is disallowed except 
that which is explicitly permitted.

But, I just do not understand what and why CD/DVD images and devices are being 
protected.  Furthermore, when virtualization changes a file's context 
(including /dev/sr0), could this effect other valid usage of these 
files/devices?  If there is no effect for other applications, then just what is 
protected?
