One approach, which might not reflect how users really install using CD media, would be to attach all CD media required to the guest during the install. The installer will always check the attached optical devices for the disc it's looking for before prompting the user. I've done this in the past, but it has the limitation that you can only attach a certain number of IDE CDROM devices to the guest at a time. With Xen, there was the xenstore-write command which could be used to change the ISO used for an attached block device. I'm not sure if there is a similar command using just libvirt? Thanks, James
