[libvirt] Mounting a raw DVD



Hello List,

I'm attempting to pass a DVD drive of a headless server into a virtual machine.  So far I've managed to mount *something* into the VM, but it's being registered as a blank DVD within the VM. When I mount /dev/dvd into the bare-metal machine it registers normally as the DVD.  How do I pass physical drives into a VM and back out using libvirt?  

Command used:
#virsh attach-disk Montreal /dev/dvd hdc --mode readonly --driver phy --type cdrom
Connecting to uri: qemu:///system
Disk attached successfully

VM XML file:
