This is my working command line: vimaowner@osprey:~$ qemu-system-x86_64 -enable-kvm -machine type=q35 \ -cpu kvm32 -m 512 -balloon none \ -drive file=virtuals/fai/fai_root.img,if=scsi,media=disk \ -drive file=cdroms/grml96-full_2014.03.iso,if=scsi,media=cdrom,readonly \ -boot order=d -name fai -vga qxl \ -spice port=5900,addr=localhost,disable-ticketing -monitor stdio Thanks a lot for showing the right path! > It is just the legacy shortcuts -hda and -cdrom doesn't work.

I think we shouldn't call it a bug and it isn't a problem if upstream is not fixing it. But we can say it's a documentation miss. I checked the manpage qemu-system-x86_64 twice and can not find a hint which says one has to use the -drive syntax with the q35 machine model. > Retitling and lowering severity accordingly. I should say we can close this bug. Thomas -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
