Re: NetBSD & disks with 4K sector size

[Greg Troxel <gdt%lexort.com@localhost>]

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,
and if so how that is communicated, and if not how the dom0 is supposed
to map things.

With any luck, this is supported and the xbd driver in NetBSD is just
not noticing the sector size variable and it's a fairly small matter of
programming.

Looking quickly at sys/arch/xen/xbd_xenbus.c, I see some concept of
sector size, but it would take me a while to understand and trace all
this.

I suggest trying a current or netbsd-10 PV or PVH domU and seeing what happens.



2) In your HVM success, do the disks appaer as 4K within the domU?
