In general, I strongly dislike passing file descriptors like this.

I find this very useful, and actually think we should encourage it, and also allow passing file descriptors over the monitor (using SCM_RIGHTS). This can help de-privilege qemu. In fact, you can run a guest where qemu doesn't even have permissions to open the backing file.
