You would also need to malloc/free the buffer you are copying to/from. I
don't know how hard that is within qemu.
I think it's ioreq_map and ioreq_unmap within hw/xen_disk.c. I had
foolishly assumed xc would do the grant copy, but it looks like
as you say I need malloc/free (or mmap equivalents) + memcpy.
Is this a useful approach to try?
