Comment 14 for bug 1716028

The important difference between your -drive command line and my -blockdev example is that I used the node-name to reference the image. You can specify a node-name with -drive, too (having both id and node-name is one of the main things that I meant what I said mixing both styles can be confusing).

I also don't think that index=1 does anything useful when used with if=none, so you can leave that out.

Putting everything together, we get this:

$ qemu-system-x86_64 \
  -drive node-name=d01,file=disk1.img,format=qcow2,if=none \
  -device virtio-blk,drive=d01,serial=s01,share-rw=on \
  -device virtio-blk,drive=d01,serial=s01,share-rw=on
