You're right, with just one latest patch things work.

Thanks for the testing. Could you test with just this patch? Since even
without 4 previous patch, we've already had the check through
virtio_queue_get_desc_addr() in
We used to set backend unconditionally, this won't work for some
guests (e.g windows driver) who may not initialize all virtqueues. For
kernel backend, this will fail since it may try to validate the rings
during setting backend.
Fixing this by simply skipping the backend set when we find desc is
10 matches
