[fedora-virt] Can't add cdrom during install

[Tom Horsley]

If I check the "customize before install" box when using
virt-manager to install a new virtual machine, then I
try to add hardware to define an extra cdrom drive for
a driver disk I'll need during install, virt-manager
gives me some error about variable 'disk' not defined
(that's what I remember, anyway, apply adequate grains
of salt :-).

Is this a known problem? Should I submit a bugzilla?

If I let the machine go ahead and start the install,
kill it, then edit the machine definition, I can
install the 2nd cd at that point.
