The xbd driver lies about the sector size and always reports 512byte
sectors. If you pass through a

The NetBSD Xen PV xbd device lies about sector

Probably best to use port-xen now that we think it's a xen thing. I
would suggest investigating everything suggested to you and then sending
a new message based on your future understanding to port-xen.
1) I am unclear on if the xbd abstraction has the concept of 4K sizes,
