QEMU creates a virtual motherboard, I add a virtual SCSI controller, to which I add a virtual optical drive that takes ISOs. This virtual SCSI controller requires a driver for Windows, but in my experience it always detects ISO changes immediately: /usr/bin/kvm \ ... -device 'virtio-scsi-pci,id=scsihw0,bus=pci.0,addr=0x5' \ -drive 'file=/spool/storage/proxmox/template/iso/virtio-win-0.1.171.iso,if=none,id=drive-scsi1,media=cdrom,aio=threads' \ -device 'scsi-cd,bus=scsihw0.0,channel=0,scsi-id=0,lun=1,drive=drive-scsi1,id=scsi1,bootindex=100' \ ... > I am adding a physical optical drive. I did not realize. Apologies for proposing an alternative that does not relate to your problem. I used to pass a physical drive like that and don't remember such problems, but I could never play DVDs or burn ISOs to discs. Therefore, nowadays, I pass-through a physical SATA controller (to a Linux VM) that has only the physical drive connected: /usr/bin/kvm \ ... -device 'vfio-pci,host=0000:0d:00.2,id=hostpci2,bus=pci.0,addr=0x1b' \ ...

(Because it is passed-through to a VM.) Maybe the following would work (after installing virtio SCSI drivers for Windows)? -device 'virtio-scsi-pci,id=scsihw0,bus=pci.0,addr=0x5' \ -drive 'file=/dev/sr0,if=none,id=drive-scsi1,media=cdrom,aio=threads' \ -device 'scsi-cd,bus=scsihw0.0,channel=0,scsi-id=0,lun=1,drive=drive-scsi1,id=scsi1' kind regards, Arjen _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
