Thanks for reviewing the patch!

I see. So do you think the patch is correct in eliminating the extra

Yes, it looks like. virtio_pci_config_read is called via a pointer
from memory_region_read_accessor and memory_region_write_accessor
calls virtio_pci_config_write.
I tested the patch in a linux/ppc64 host with a FreeBSD/ppc64 guest
and VirtIO 0.9 (legacy) driver and from what I saw the config area
