That's the easy part though, and part of what I want to change.

All we need is the index of the request; the rest can be re-read from
the ring.  So create the array in pre_save, and restore on post_load.

Is there something more recent than
http://repo.or.cz/w/qemu/quintela.git/shortlog/refs/heads/vmstate/virtio
or should I cherry-pick from there?

Thanks,
Rusty.
