Yes, I think we sould pass option to qemu command line.
But If I understand, It should work without it, but slowly.

But I don't have hardware to test it :(

So I guess we should pass: 

-device virtio-blk-pci,logical_block_size=4096,physical_block_size=4096,.... 

when the underlying drive uses 4K blocks. 

Is there an easy what to detect sector size? 

Or should that be a storage option?
