--- Comment #1 from Alexander Motin <mav at FreeBSD.org> ---
I don't think this is a bug, more like a feature request.

ZVOL in that place behaves exactly like 512e (Advanced Format) HDDs. Last time
it even reports its block size as stripesize property to GEOM, and CTL now
announces that size to the iSCSI layer as disk's physical sector size size.

I have no idea whether VirtualBox supports reporting physical sector size, or
large sectors at all, but I think it should.
