With QEMU v2.0.0, real cdroms don't work. A quick look at the output from the "info block" command shows this: ide1-cd0: /dev/cdrom (raw, read-only) Removable device: not locked, tray closed This indicates that the cdrom is set to /dev/cdrom. I remember versions of QEMU prior to 1.5 were able to use a real cdrom. qemu-system-ppc is being run on Mac OS 10.6.8. According to https://bugs.launchpad.net/qemu/+bug/588691 CD-ROM drives should be working again, so I assume we can close this bug nowadays? Or can you still reproduce it with the latest version of QEMU? > On Sep 24, 2018, at 5:14 AM, Thomas Huth
