[Users] engine refuses to add cdrom device to my vms

[Adam Litke]

Hello,

I am currently experimenting with an all-in-one setup (engine and vdsm on same
host).  I have my storage configured (data/iso/export domains all attached) and
my local host is Up.  When I try to create a VM with a CDROM device the VM
starts but has no CD device at all.  Any ideas why this would be happening?

I am not seeing anything here to indicate why the cdrom is being omitted.  Confused.
