vioblk should support the TOPOLOGY feature for physical block size reporting
There's a virtio-block feature called TOPOLOGY that allows the driver to receive (among other things) a physical block size from the hypervisor. This should be used to report the physical block size of the underlying media in DKIOCGMEDIAINFOEXT, to be consumed by ZFS.
