[libvirt] [PATCH v1 00/11] Rework storage migration

How does this series interact with Li Guang's efforts to add offline
migration?  In particular,

> 1)  src -> dest: (QEMU_MIGRATION_PHASE_BEGIN3 ->
> QEMU_MIGRATION_PHASE_PREPARE)
>     <nbd>
>        <disk src='/var/lib/libvirt/images/f17.img'
>        size='17179869184'/>
>     </nbd>

Both sets of patches need to pass size information across in the
cookies; so is tying it to <nbd> appropriate, or should we be
rethinking this XML to be shared between both patches?
