Create a VM which should install from CD. Remove the CD, then try to boot. You will be presented with a very ugly error window (see screenshot). VMM should catch this error and just ask for a CD.

I'm not sure that's possible - it's no different from e.g. someone deleting a guest disk image from the command line just before starting a guest. "internal error" is a bit bogus, I admit

I don't think I can describe better than in comment #0 :) > it's no different from e.g. someone deleting a guest disk image > from the command line just before starting a guest It's much more likely that someone starts a VM which relies on a *mounted* CD than someone deleting a disk image by hand I think. Anyway, I'm not talking about ejecting a CD after pressing "start vm". You could for example configure a CD, reboot the physical box, run virt manager again and now try to start the vm.
