This is the next part of virtio-refactoring.
I send it now to have it reviewed.
Basically it creates virtio-blk device which extends virtio-device.
Then a virtio-blk can be connected on a virtio-bus.
virtio-blk-pci, virtio-blk-s390x, virtio-blk-ccw are created too, they extend
respectively virtio-pci, virtio-s390-device, virtio-ccw-device and have a
virtio-blk.
It is on top of "virtio: make virtio device's structures public" I posted
before, but you can checkout my branch here:
git://git.greensocs.com/qemu_virtio.git virtio-blk-v4
I made basic tests (with linux guests) on:
* qemu-system-i386
* qemu-system-s390x
I didn't test dataplane as I don't know how it works? Depends on linux AIO?
Stefan can you try launching dataplane with my tree?
I didn't test virtio-ccw as I don't have the hardware.
Anyone can try it on ccw hardware?
Thanks.
Fred

Is this ok, for everybody?
I did basic test with x86 guest and s390x,
Cornelia reported that it works for CCW too.
I can't test dataplane as it seems not to work with TCG.
Thanks,
Fred
