Here the virtio-blk-pci is modified for the new API. The device virtio-pci-blk
extends virtio-pci. It creates and connects a virtio-blk during the init.

Did you check whether this maintains backwards compatibility
for vmstate migration information and device properties?
(haven't investigated myself yet, just asking whether you have)

-- PMM

What do you mean exactly by backwards compatibility for vmstate migration ?

The device properties didn't change.
The virtio-blk-pci creates a virtio-blk device, puts the virtio block properties and inits the virtio-blk.
