Unfortunately not, see virtio_blk. capacity is 64 bits, and geometry is multiple fields. > If we're already making the change, the endianness ought to be a feature bit. I'd rather tie it to the new PCI config layout (and ring format). Then we can simply have two backends, legacy and modern. For non-PCI, we would need a feature bit.
