Commit ed65fd1a27 restricted the 'scsi' property to Linux hosts: 1261 static Property virtio_blk_properties[] = { 1262 DEFINE_BLOCK_PROPERTIES(VirtIOBlock, conf.conf), ... 1268 #ifdef __linux__ 1269 DEFINE_PROP_BIT64("scsi", VirtIOBlock, host_features, 1270 VIRTIO_BLK_F_SCSI, false), 1271 #endif
When we try to set this property on a pre-2.4 machine on OSX, we get: Unexpected error in object_property_find() at qom/object.c:1201: qemu-system-x86_64: -device virtio-blk-pci,id=scsi0,drive=drive0: can't apply global virtio-blk-device.scsi=true: Property '.scsi' not found Fix this error by marking the property optional.
