It looks like the "short" -drive if=ide option does not connect the
created drive to any bus at all.  With the above command, or with
-drive if=ide,index=*,bus=*, info qtree does not show the drive at
all.  While -drive if=none,id=X -device ide-cd,drive=X connects the
drive to the right bus just fine.

Again, should this drive be visible in qtree?  At least with -M pc,
similarly added devices are shown properly there.

Thanks,
