Does it exist?
What about kernel add-on packages
that would insert the pseudo-driver shim
and the apps to use it?

If you mean, for instance, can I put an ISO image on my HD and mount it, then it's built in to the Kernel:

mount -t iso9660 -o loop,ro <path to image> <mount point>

Hi Andy,
no, that is not what I meant. I really mean a cd/dvd/optical media
hardware device emulation,

and not the FS support of iso9660.

I read some blogs about cdemu, which is not
available in the fedora repos.

I don't believe so. You probably need something like:

http://cdemu.sourceforge.net

which incidentally does work quite well but you'll need to go through
the pain of building it yourself. There is also an iSCSI hack which lets
you create a virtual optical device and even share that as a block
device over the network being iSCSI. You can even burn DVDs to it, with
the end result being an ISO, but for all intents and purposes it appears
to be a physical optical device. I seem to remember its
scsi-target-utils and you'll probably also want iscsi-initiator-utils to
use it. Both of which are in Fedora.

Yes, although the utility of that is questionable. No emulator will let you do
things like a proper rip of a CD, because the fancy subtrack and odd preburn
areas and such aren't in your image. And if you are debugging optical media
drivers, I doubt any emulation will be a bizarre as burner firmware.


You can get a better emulation by using kvm, starting qemu-kvm with the -cdrom
option, but what you need to emulate is the optical media device, as well as the
media itself, and the accuracy of emulation is dubious.
